    8x + y = –18 –8x + y = –18 8x – y = –18 8x + y = 18

    use y=mx + b where, m = slope b = y-intercept (the y-intercept is the point where x = 0)

    Just sub the slope that is given, and the x and y value of the point and solve for b. Remember a point in this case is defined as (x,y)

    once you have solved for b just sub along with the slope into the equation y = mx + b remember the y value is the output and the x value is the input, so they are changing the slope and y-intercept are constants

    -8(-2) + b = (-2) b = -16 - 2 b = -18 y = (-8)x + (-18)
