Answer:
a. y=-3/2x-7
Step-by-step explanation:
First, you make the equation into slope intercept form, which is y=2/3x-3.
Then, because its perpendicular, the slope turns negative and upside down, so its -3/2, and then you insert the point (4, -1) to get the y intercept, which is -7. So you're answer is a.
