Question 760336
Find the gradient y2 - y1/x2 - x1
               =   6 - 3/9 -(-5)
               = 3/14
Using equation: y - b = m(x - a)
                y - 6 = 3/14(x - 9)
                y - 6 = 3/14x - 27/14
                    y = 3/14x - 27/14 + 84/14
                    y = 3/14x + 57/14
Multiply through by 14
                   14y = 3x + 57
Hope this helps.
