Answer:
(11/4) is the slope
Step-by-step explanation:
1) Subtract the second y value (-9) by the first y value (2) in the coordinates. This equals 11.
2) Then, subtract the second x value (-3) by the first x value (1) in the coordinates. This equals 4.
3) Divide the answer you get for step one by the answer for step 2 and that's your slope. 11/4
