what's up? we can find slope with rise/run. ill do the first dotted line on top.
the rise/run formula is y2 - y1/x2 - x1
1: (7,3)
2: (-8, -2)
-2 - 3
-8 - 7
-5/-15
this is the same as 1/3 which is your slope for the first answer
i will pick my own 2 points for the second question.
1: (-2, 5)
2: (0, -1)
-1 - 5
0 - -2
we can change the negatives out for positives to make
-1 - 5
0 +2
this makes -6/2, which is also -3 and that is your answer for the second question. good luck!
