Which of the following represents a line that is perpendicular to the line with the equation y=-2x-5 a. y-2=-½ (x-3)
b. x-2y=12
c.-2x+4y=10
d. y-2=2(x+5)

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
