Given (-4,y0) is a point on the following line, convert the equation to point-slope form. y = 3x + 5

The equation is a second degree equation so it will have 2 solutions.
theeasiest way to solve this equation is the 'square root method'.
first i'll get the 'square on the left and everything else on the right.
(x - 4)^2 -28 = 8
add 28 to both sides.
(x - 4)^2 = 36
take the square root of both sides
x - 4 = + - 6
add 4 to both sides.
x = 4 + - 6
x = 4 + 6 = 10
x = 4 - 6 = -2
