Question

Which statement is true about the slope of the line and what it means in this

situation?
The slope of the line is 1. This means that Jan runs 1 lap every minute.
The slope of the line is 2. This means that Jan runs 2 laps every minute.
I
The slope of the line is 2. This means that Jan runs 1 lap every 2 minutes.
The slope of the line is 4. This means that Jan runs 4 laps every minute.

Answer 1

• (0,0)
• (2,4)

Slope

• m=4-0/2-0
• m=4/2
• m=2

Rate is 2 laps every minute

• B

Answer 2

• B. The slope of the line is 2. This means that Jan runs 2 laps every minute.

Explanation:

This is a proportional relationship as the line passes through the origin.

Therefore you can use one point to determine the slope, (2, 4):

• m = y/x = 4/2 = 2

The slope is 2. It is a 2 laps per minute.

Correct answer choice is B
