she drove 40 mph & 60 mph
60 +40 = 100
100/2 = 50
so she drove an average of 50 mph
Answer:
I think it's (0,1) x=0, y=1
Sorry if that's wrong
It’s 20 I believe. All together it should be 160 so you add 118 and 22 to get 140. Then subtract that from 160 and you get 20.
Slope is equal to rise over run. For this question we use 0-6=-6 as the numerator and 9-7=2 as the denominator, thus the slope is -6/2=-3
Slope: (y2-y1)/(x2-x1)
(8-2)/(1+1) = 6/2 = 3
The slope is 3
