    y = 4x + 10 y = one fourthx + 5 halves y = -4x - 6 y = -one fourthx + 3 halves

    y = (slope)*x + (intercept) y = m *x + b

    If one line is parallel to another, they will have the same slope m

    so the slope is 4 and they gave you a point (x,y) = (-2 , 2) You know everything but the y intercept now, b y = m*x + b plug in and solve

    2 = 4*(-2) + b

    yes, so the line parallel has slope --- m = 4 y-intercept --- b = 10 y = m*x + b
