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)

Question

anonymous · Answer

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:
$$-1/-1 = 1$$

anonymous · Answer

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

anonymous · Answer

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
