+277 Calculate the slope.
1. (2, -3) (5, 8)
2. (0, 4) (7, -10)
3. (-2, -9) (6, 0)
4. (3.5, 9) (2.5, 8)
+23246 The formula for slope is: m = (y2 - y1) / (x2 - x1)
For problem #1, let (x1, y1) = (2, -3) and (x2, y2) = (5, 8).
---> x1 = 2 y1 = -3 x2 = 5 y2 = 8
---> Substitute into the slope formula: (8 - -3) / (5 - 2) = 11/3
Use this example to work the other three problems.
