Slope Intercept Line Equation:   y = mx + b        m is slope and b is y-intercept Given Line:  y = 8x + 4   slope (m) is 8 (coefficient of x) Parallel lines have the same slope, so slope (m) of our parallel line will also be 8. Given point our parallel line is to pass thru is (-1,3), where x is -1 and y =3. Plugging these values into our slope-intercept equation (y = mx + b), we get:   3 = 8(-1) + b Solving for b:   3 = -8 + b   b = 3 + 8 = 11 So our final equation is:   y = 8x + 11
