The plot line shows the number of miles the individual members in a group of runners run each day

how many runners run at most 2 miles per day?

13

Step-by-step explanation:

2 miles = 6

3 miles = 4

4 miles = 2

5 miles = 1

Add them together to get 13 miles, the only people who don’t run at least 2 miles are the people who ran only 1 mile.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
