Answer 2

Answer: The answer is (D) 19 miles.

Step-by-step explanation: We are given a graph that represents the running schedule of a distance runner, who is increasing the distance she runs each week. We are to find the distance she will run in the ninth week.

In the graph, the number of week are represented by the X-axis and the distance run is represented by the Y-axis.

Since we are to find the distance run in the ninth week, so we will have to find the value of y when the value of x is 9.

We can see from the graph that when x = 9, then y = 19, as (9, 19) is a point on the graph. So, the distance run in the ninth week is 19 miles.

Thus, (D) is the correct option.
