Write an equation in slope-intercept form for the line.

Question

1. Perpendicular to 5x + 2y = 8 and through (5,3).

A: y = -1/5x + 4?

Answer 1

2 y = -5 x + 8

y = -(5/2) x + 4

slope = -5/2 so slope of perpendicular = 2/5

y = -(2/5) x + b
3 = -(2/5)5 + b
3 = -2 + b
b = 5

y = -(2/5) x + 5

Answer 2

Wouldn't the slope be -1/5?

Answer 3

nope,,
Damon showed you that the slope of your given line is -5/2
