Question

identifiy an equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1)

Answer 1

Hey there!

A line perpendicular to y=3x+5 would have a slope of -1/3.

Thus, the problem now becomes to write a line in point slope form with a slope of -1/3, and that passes through (4, -1)

y+1=-1/3(x-4), would be your answer.

Hope this helps :)
