Question

(-1, 3) and perpendicular to y = -one thirdx + 7.

y = 3x - 12

y = 3x + 6

y = 3x - 6

y = 3x

Answer 1

Well, from the choices we can guess that the slope of that line is going to be 3>

We can verify by taking -1/3, flipping it and changing the sign.

So m = 3.

At this point, we should use the point slope formula.

\[y-y _{0}=m(x-x _{0})\]

Answer 2

y-3=3(x+1)
y=3x+6

Answer 3

So:

y - 3 = 3 (x- (-1)
y - 3 = 3x + 3
y = 3x + 6
