Answer:
B) 5 hours
Step-by-step explanation:
First, find the amount of mph between 60 and 80:
80 - 60
= 20 mph
Since the speed increases 4 mph per hour, we can find how long it will take to get to 80 mph by dividing 20 by 4:
20/4
= 5
So, the correct answer is B, 5 hours

Answer:
-3
Step-by-step explanation:
Slope of a line is "rise over run". Pick two points on the line. For example, (0,4) and (1,1). As we move from the first point to the second, we move down 3 units and right 1 unit. So the slope is -3/1 = -3.
Here's an algebraic approach. If the two points are (x₁, y₁) and (x₂, y₂), then the slope is:
m = (y₂ − y₁) / (x₂ − x₁)
Plugging in our two points:
m = (1 − 4) / (1 − 0)
m = -3
