pick 2 sets of points from ur table...
(-4,-16)(-2,-6)
slope = (y2 - y1) / (x2 - x1)
slope = (-6 - (-16) / (-2 - (-4) = (-6 + 16) / (-2 + 4) = 10/2 = 5
u could pick any 2 of ur sets of points.....it will come out the same...let me show you...
(2,14)(4,24)
slope = (y2 - y1) / (x2 - x1)
slope = (24 - 14) / (4 - 2) = 10/2 = 5...see, it is the same no matter what 2 sets of points u choose)
