How do you find the equation of a line?

How to Find the Equation of a Line from Two Points

  1. Find the slope using the slope formula.
  2. Use the slope and one of the points to solve for the y-intercept (b).
  3. Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.

How do you show the equation of a trendline in Excel on a Mac?

What is Y MX B?

y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation ‘y = mx + b’, ‘b’ is the point, where the line intersects the ‘y axis’ and ‘m’ denotes the slope of the line. The slope or gradient of a line describes how steep a line is.

How do I get R2 in Excel for Mac?

How do you find r 2?

To calculate R2 you need to find the sum of the residuals squared and the total sum of squares. Start off by finding the residuals, which is the distance from regression line to each data point. Work out the predicted y value by plugging in the corresponding x value into the regression line equation.

What does R 2 indicate?

R-squared (R2) is a statistical measure that represents the proportion of the variance for a dependent variable that’s explained by an independent variable or variables in a regression model.

How do you find the equation of a trend line in a scatter plot?

FINDING THE EQUATION OF A TREND LINE

  1. When a linear association is shown by a scatter plot, we can use a line to model the relationship between the variables.
  2. m = (y2 – y1) / (x2 – x1)
  3. Substitute x1, = 2, y1 = 20, x2 = 4, and y2 = 45.
  4. m = (y2 – y1) / (x2 – x1)
  5. Substitute x1, = 5, y1 = 50, x2 = 17, and y2 = 170.

How do you display Formulas in text?

You may have set the cell formatting to “Text” and then typed the formula in it. When you set the cell formatting to “Text”, Excel treats the formula as text and shows it instead of evaluating it.
