Answer:

The Answer is: y = 1/4x + 6

Step-by-step explanation:

Given point (8, 8)

Given equation: 4x + y = 5

Solve for y:

y = -4x + 5

The slope is -4. The slope of a perpendicular line is the negative inverse, which would be 1/4.

Use the point slope form:

y - 8 = 1/4(x - 8)

Solve for y:

y - 8 = 1/4x - 8/4

y - 8 = 1/4x - 2

y = 1/4x - 2 + 8

y = 1/4x + 6
