    (y-y1)/(y2-y1)=(x-x1)/(x2-x1) for first que (y2-y1)=m(x2-x1)

    slope=(y2-y1)/(x2-x1) point slope form= y-y1=m(x-x1)

    (-2, 6) and (7, -1): 6 = -2m + b -1 = 7m + b b = 6 + 2m b = -7m - 1 b = b 6 + 2m = -7m - 1 7m + 2m = -6 - 1 9m = -7 m = -7/9 b = 6 + 2(-7/9) b = 6 -14/9 b = 54/9 - 14/9 b = 40/9 y = -7/9(m) + 40/9
