Answer 1

Answer:

D.

Step-by-step explanation:

I have been doing this in Geometry.

We know perpendicular means opposite recipicoles and opposite slopes.

so.. the slope is 3 to get the y-intercept you do this.

(1, 2) Use the points it gave you and the slope 3 and put it is y=mx + b form

2 = 3(1) + b (I do this because I don't know what b is yet) (b = y-intercept)

2 = 3 + b (subtract 3 on both sides)

-1 = b

The equation is y = 3x - 1
