Answer:
Step-by-step explanation:
6) Slope = 5
(5 , 40) ; m =5
y - y1 = m(x -x1)
y - 40 = 5 (x - 5)
y -40 = 5x - 25
y = 5x - 25 + 40
y = 5x + 15
7) slope = 2
m =2 ; (-2 , 0)
y - y1 = m(x -x1)
y - 0 = 2(x -[-2])
y = 2(x +2)
y = 2x +4
8) D) It takes 6 miles to travel a mile
7 7 / 1 7 x 3 21
--- = ---------- = ------------- = --------- = 21 miles per gallon
1/3 1 / 3 1 x 1 1
