Question

About what is the average change in distance for each increase of 1 in the iron number? What does this mean in terms of the situation?

Answer 1

Given

The graph is given with the x-axis iron and y-axis distance in yards.

Step-by-step explanation

To determine the average change in distance for each increase of 1 in the iron number

The coordinates from the graph is

`(3,155),(4,145)`

The average rate of change is determined as

`m=(y_2-y_1)/(x_2-x_1)`

Substitute the values.

`\begin{gathered} m=(155-145)/(3-4) \\ m=(10)/(-1)=-10 \end{gathered}`Answer

Hence the average change in distance for each increase of 1 in the iron number is -10.

The situation represents that the distance decrease by 10 yards for each number of iron.
