What is the slope of a line perpendicular to the line represented by the equation 2y = -6x + 8?

slope=-1,

Step-by-step explanation:

first you have to find the slope of the original question

2x+2y=-8

2y= -8 -2x

y= -4-x

slope = -1

to find the perpendicular slope you flip it and multiply by -1

-1 -> -1 *-1 -> 1

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
