Question

Write the equation of the perpendicular line with the points (-9,2) with the equation 3x-y=12

Answer 1

y=-1/3x-1

Explanation:

Perpendicular lines have slope that are opposite sign and reciprocals

3x-y=12 has a slope of 3, therefore perpendicular line must have slope of -1/3

2=-9(-1/3)+b

2=3+b

b=-1
