Question

I need help with this

Answer 1

i’m 70% sure it’s y=-5/4x -8

Answer 2

Answer: y = (-5/4)x - 8

========================================================

Step-by-step explanation:

Recall that y = mx+b is the slope intercept form of any linear equation

• m = slope
• b = y intercept

The given equation has m = 4/5 as the slope. Flip the fraction to get 5/4 and then flip the sign to get -5/4

The original slope is 4/5 and the perpendicular slope is -5/4. Note how the slopes multiply to -1.

The slope for the answer is -5/4 and the y intercept for the answer is -8

Therefore, the perpendicular line is y = (-5/4)x - 8
