Equation of line passing through (4, 12 and (4,-8)

First we calculate the Slope = m = (Y2 -Y1) ÷ (X2 -X1)

(-8 -12) / (4 -4) Slope = 90 degrees

Line is vertical   Equation would be:

X = 4

the correct answers i think are b. and d.

give me brainliest if it is correct!

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
