Question

Give the slope intercept form of the equation of the line that is perpendicular to -4x -8y = 10 and contains P(-8, -4)

Answer 1

Answer:

y = 2x + 12

Step-by-step explanation:

Get the standard form equation into y = mx + b form.

Then, use the recipricol of the m value to get the slope for the perpendicular line.

Then, plug in the point and solve for the b value.

Work :

y = -1/2x-5/4

Perpendicular line slope : 2

y = 2x + b

-4 = 2(-8) + b

-4 = -16 + b

b = 12

y = 2x + 12
