Answer:
-2
Step-by-step explanation:
From the given graph, the point A(1, -4) and B(-1, 0)
Slope (m) = (y2 - y1) / (x2 - x1)
x1 = 1, y1 = -4, x2 = -1 and y2 = 0
Slope (m) = (0 - (-4))/(-1 - 1)
= 4/-2
Slope = -2

Step-by-step explanation:
5 incorrect means 45 correct answers
45/50 = .90×100=90%
Answer:
135 gallons
Step-by-step explanation:
gallons of a 50% + 90 gallons of 25% = mixture that is 40%
50x + 25(90) = 40(x + 90)
50x + 2250 = 40x + 3600
10x = 1350
x = 135
