Slope Formula Calculator Enter any Number into this free calculator. M Y 2 Y 1 X 2 X 1 The answer M is the slope of the line. Slope calculator uses coordinates of two points AxAyA A x A y A and BxByB B x B y B in the two-dimensional Cartesian coordinate plane and find the slope coefficient of a line that passes through A A and B B.

Step OneIdentify two points on the line. Now you can correctly pick out the value for which is -7 and which is -9. If you know the rise and run of a line you can calculate its slope using the slope formula. The correct form is y - -7 3x - -9.
