Answer:
y = -9x - 6.
Step-by-step explanation:
To find a perpendicular line, take the number attached to x from your normal line, flip it, and then switch its sign.
So you have y = 1/9x - 1.
Ignore the -1 here, it does not matter.
1/9 flipped is 9/1, which is 9.
Make it negative.
So the new line will have a slope of -9.
y = -9x + b.
To solve for b, plug in -1 for x and 3 for y.
3 = 9 + b.
So b is going to be -6.
