Answer
(a) 0.600
(b) 5.
(c) decreases.
Work Step by Step
Earned run average is plotted on the x-axis and winning percentage on the y-axis.
(a) When we draw a horizontal line from the point that has an x-value of 4.2, it crosses the y-axis at 0.600.
So, the winning percentage of the pitcher with an earned run average of 4.2 is 0.600.
(b) When we draw a vertical line from the point that has a y-value of 0.33, it crosses the x-axis at 5.
So, the earned run average of the pitcher with a winning percentage of 0.33 is 5.
(c) As the plotted points go bottom from left to right, the winning percentage decreases as the earned run average increases.
