The graph represents the heights of two climbers on a climbing wall over a 12-minute time period.

how high did abby climb above their original starting position?

8 feet
15 feet
18 feet
22 feet

Abby climb 18 feet above from the original starting position.

Step-by-step explanation:

Consider the provided graph.

We need to find How high did Abby climb above their original starting position?

In order to find the how high Abby climb we need to find the difference of  highest and the height at the starting point,

The difference of the height will provide the distance climb by Abby.

The starting height is 4 feet and the highest height is 22 feet.

Subtract 4 from 22

22-4=18

Hence, Abby climb 18 feet above from the original starting position.
