-9x + y = 39 y = 9x + 39 The y-intercept is where x = 0 Therefore the y intercept is where: y - 9(0) = 39 y = 39 The y intercept is 39 The x-intercept is where y = 0 Therefore the y intercepet is where: 0 - 9x = 39 - 9x = 39 9x = - 39 x = -39/9
39 + 39 + 39 + 39 + 39 + 39 = 234
b = 12 12(3)+3 = 39, use a calculator to find out
