Determine slope of any line perpindicular to GH. (-1,2) (-2,-1)

Perpendicular slope = – 1/m = -1/3 = -1/3

Step-by-step explanation:

Given the points

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = 3

perpendicular slope = – 1/m = -1/3 = -1/3

Thus, the slope of any line perpendicular to GH = -1/3

answer is 67%

step-by-step explanation:

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
