Question

given two points M and N on the coordinate plane, find the slope of line MN, and state the slope of the line perpendicular to line MN:
M(-2,2) N(4,-4)

Answer 1

The slope or gradient of the line is:
\[((-4)-(2))/((4)-(-2)) = -1\]
And the gradient of the perpendicular line is the negative reciprocal, that is:
\[-1/-1 = 1\]

Answer 2

(2--4)/(-2-4)=-1. slope perpendicular is 1.

Answer 3

the formula to find the slope is below
\[ m = \frac{y_{2}-y_{1}} {x_{2}-x_{1}} \] m=slope
Just plug your points in and do the math
