Line m contains (6,8) and (-1,2). line n contains (-1,5) and (5,y). what is the value of y if line m is perpendicular to line n

y=-37

Step-by-step explanation:

A perpendicular line has a negative reciprocal slope to the original line. We will use the slope formula to find the slope of line m, then take the negative reciprocal for the slope of line n which will reveal the value of y.

Slope:

We substitute and

for line n because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is .

We will substitute into the slope formula to find line n's coordinate value y. We will also substitute and   .
