(-3,-1)(3,2) slope = (2 - (-1) / (3 - (-3) = (2 + 1) / (3 + 3) = 3/6 = 1/2 y = mx + b slope(m) = 1/2 use either of ur points ..(3,2)...x = 3 and y = 2 now we sub and find b, the y int 2 = 1/2(3) + b 2 = 3/2 + b 2 - 3/2 = b 4/2 - 3/2 = b 1/2 = b ur equation is : y = 1/2x + 1/2....but we need it in standard form.. y = 1/2x + 2...subtract 1/2x from both sides -1/2x + y = 2..multiply everything by -2 x - 2y = -4 <== standard form
