What is the value of y when the slope of the line that passes through points (2,4) and -2,y) is 12?

Question

I know how to do slope intercept and slope form but I don't know how to solve for the y in this case.  I need to know the steps.

Answer 1

???????? slope=12 ????

& go thru point=(2,4)

projekt bak from x=2 tu x=0 tu get y

deltax=-2, deltay=slope*deltax=12*-2=-24

y-intersept=4-24=-20

point=(0,-20)

y=12x-24

for NE other x, plug x number intu quashun & get y
