In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

How do you find the intercept?
College Algebra
- To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
- To find the x-intercept, set y = 0 displaystyle y=0 y=0.
- To find the y-intercept, set x = 0 displaystyle x=0 x=0.
What is intercept?
Definition of y-intercept
: the y-coordinate of a point where a line, curve, or surface intersects the y-axis.
What are some examples of intercept?
When you prevent someone from walking into a room this is an example of a time when you intercept the person. When a quarterback throws a ball to his receiver and instead you jump up and catch it, this is an example of an intercept. To stop, deflect, or interrupt the progress or intended course of.
How do you find the intercept form?
- Remember, intercept form is y = a(x-p)(x-q)
- Now that we have a value for ‘a’, we can plug that into the equation we had before to get our final equation in intercept form.
- The equation we end up with is y = 2(x+3)(x-1)
How do you find slope and intercept?
Use the formula y = mx + b, where m is the slope and b is the y-intercept. How do I write the equation of a line, given the slope and y-intercept? Assuming you’re talking about a linear (straight-line) equation, you would use the standard slope/y-intercept form, y = mx + b.
What is linear in math?
Linearity is the property of a mathematical relationship (function) that can be graphically represented as a straight line.The word linear comes from Latin linearis, “pertaining to or resembling a line”.
What is slope-intercept form in algebra?
The slope-intercept form of a linear equation is where one side contains just “y”. So, it will look like: y = mx + b where “m” and “b” are numbers. This form of the equation is very useful. The coefficient of “x” (the “m” value) is the slope of the line. And, the constant (the “b” value) is the y-intercept at (0, b)
What is a vertical intercept in math?
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.
What does intercept mean in statistics?
The intercept (often labeled the constant) is the expected mean value of Y when all X=0. Start with a regression equation with one predictor, X. If X sometimes equals 0, the intercept is simply the expected mean value of Y at that value.It’s the mean value of Y at the chosen value of X.
How do you find the intercept of a graph in physics?
2 Answers By Expert Tutors. m is the slope, and b is Y intercept. Y intercept is the point which graph of line crosses the Y- axis , all points on the y axis have X =0. So if in equation Y = mx +b , let X = 0 , then Y = m(0) = b , and b is the Y intercept.
What is intercept form in Algebra 2?
The intercept form is y = a(x – r)(x – s), where r and s are the x-intercepts on the graph. The intercept form will tell us if there are two x-intercepts, one x-intercept or no x-intercepts.
How do you use intercept?
To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation. To graph a line, find the intercepts, if they exist, and draw a straight line through them.
What is the intercept form of the line?
The intercept form of the equation of a line is x/a + y/b = 1. This is one of the important forms of equations of a line. Also, the sign of the intercepts in this equation help us to know the location of the line with respect to the coordinate axes.
Is B the y-intercept?
In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the “slope-intercept form”.
How do you find the intercept of two lines?
How Do I Find the Point of Intersection of Two Lines?
- Get the two equations for the lines into slope-intercept form.
- Set the two equations for y equal to each other.
- Solve for x.
- Use this x-coordinate and substitute it into either of the original equations for the lines and solve for y.
What does constant mean in math?
The terms mathematical constant or physical constant are sometimes used to distinguish this meaning.A function whose value remains unchanged (i.e., a constant function). Such a constant is commonly represented by a variable which does not depend on the main variable(s) in question.
What does equation mean in math?
equals symbol
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in maths when you do not know the exact number in a calculation.
What is the value of H?
The symbol h is used to express the value of the Planck constant in J⋅s/cycle, and the symbol ħ (“h-bar”) is used to express its value in J⋅s/rad.
Planck constant.
| Constant | SI units | Units with eV |
|---|---|---|
| h | 6.62607015×10−34 J⋅Hz−1 | 4.135667696…×10−15 eV⋅Hz−1 |

How do u write an equation in slope-intercept form?
The slope-intercept form is one way to write a linear equation (the equation of a line). The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It’s usually easy to graph a line using y=mx+b.
What is a horizontal intercept?
An intercept is a point where the line or curve passes through the axis of the graph. When a point crosses x axis then that point is called x intercept or horizontal intercept.
