Answer:
m = -1/2
Step-by-step explanation:
Recall that slope = (change in y) / (change in x).
Going from (−8,−1) to (−6,−2), x increases by 2 (because -6 - (-8) = 2), and
y decreases by 1. Thus, the slope here is
m = (change in y) / (change in x) = (-1) / 2 = -1 / 2
m = -1/2
70=3x+10
Subtract 10 from both sides
60=3x
Divide both sides by 3
20=x
x=20
