The answer to the problem
aliya0001 [1]
<h3>Answer:  -2/3</h3>

================================================

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (8-6)/(2-5)

m = (2)/(-3)

m = -2/3

As you can see, we subtract the y coordinates together. We also subtract the x values together in the same order. If the order is mixed up, then you'll get the wrong sign for the final answer.

The slope is equal to rise over run. Think of "rise" as "change in y", which explains the difference in y values. The run is equal to the change in x, which is the difference in x values.

Papessa [141]

Answer: 75 minutes per hour.

Step-by-step explanation:

From the question, we are informed that Marion is driving between two towns that are close together and that she drives 1/5 the distance of the trip in 15 minutes.

The rate per hour will then be:

= 15 ÷ 1/5

= 15 × 5

= 75 minutes

The rate per hour will then be 75 minutes per hour.
