At x = -2, y = -4 At x = 1, y = 3 You have two pairs (1,3)(-2,-4). You have to figure out the rate of change (y2-y1)/(x2-x1) (-4-3)/(-2-1) Which the answer is b 7/3 hope this helps.
At x = -2, y = -4 At x = 1, y = 3 This gives you two ordered pairs (1,3) and (-2,-4). Use the slope formula to find slope(rate of change) (Y2-y1)/(x2-X1) (-4-3)/(-2-1) M = -7/-3 = 7/3
