y-y1 = m(x-x1)
(x,y) is a point on the line; m=slope
find two points on the line, use the slope formula to find the slope.
y2-y1 / x2-x1
the product is your slope (m).
choose one of the points to use in your equation, and simply plug in the numbers.
points: (-2,0) (0,4)
4-0 / 0+2
now choose one of the points, and plug-in your numbers.
i'll choose (0,4)
which would simplify to:
