INTERCEPT

Formulas / INTERCEPT
Calculate the intercept of a regression line.
=INTERCEPT(known_y's,known_x's)
  • known_x - required, independent set of data
  • known_y - required, dependent set of data

Examples

  • =INTERCEPT({2;0},{-1;1})

    The function is used to calculate the point of intersection between two linear functions. For example, the function returns 1 because the first argument is {2;0} which is the line 2x+0 and the second argument is {-1;1} which is the line -1x+1. The result is 1, which is the point of intersection between the two linear functions.

  • =INTERCEPT({2;3},{-1;2})

    The function can be used to calculate the slope of a line. For example, the function returns -1. This is because the first argument is {2;3} which is the line 2x+3 and the second argument is {-1;2} which is the line -1x+2. The result is -1, which is the slope of the line.

  • =INTERCEPT({3;-2},{1;3})

    The function can also be used to calculate the y-intercept of a line. For example, the function returns -2. This is because the first argument is {3;-2} which is the line 3x-2 and the second argument is {1;3} which is the line 1x+3. The result is -2, which is the y-intercept of the line.


Summary

The INTERCEPT function allows users to calculate the intercept point of a line by providing existing x-values and y-values. It is a simple and convenient way to calculate this point without having to manually calculate it.

  • The INTERCEPT function calculates the intercept of a regression line, using an array or range of known_ys and known_xs values as arguments.
  • The INTERCEPT function can be used to calculate the value of a dependent variable when the independent variable is zero.
