Answer:
-5/24
Step-by-step explanation:
You first change -7/12 to -14/24, and 3/8 to 9/24 so they have the same denominator. You then do -14/24 + 9/24. That will be the same as the opposite of the answer to 14/24 - 9/24.
14/24 - 9/24 = 5/24
-5/24
Well if the first point is (-2, 1) and the slope is three than the other point would be (-1, 4)
