Question

Write the point slope form of the line passing through 2,-12 and parallel to y=3x

Answer 1

The formula is "

(y2-y1) = m(x2-x1)===> since this is parallel to y=3x, that means both have the same slope, that is 3:

(y2-y1) = 3(x2-x1)===>y+12 = 3x -6 or y=3x-18

Answer 2

y-y1=m(x-x1)
y+12=3(x-2)
y+2=3x-6
y=3x-8
