A. A coordinate plane with four quadrants shows the x and y axes ranging from negative 8 to 8 in increments of 1. An upward line with arrows on both the ends passes through the first, fourth, and third quadrants. The line intersects the x-axis at left parenthesis 0.3 comma 0 right parenthesis and the y-axis at left parenthesis 0 comma negative 1 right parenthesis. Values are approximate.

A. A coordinate plane shows the x-axis, labeled as Number of Minutes, ranging from negative 2 to 30 in increments of 2, and the y-axis, labeled as Page Number, ranging from negative 5 to 100 in increments of 5. A ray extends from a plotted point. The coordinates of a plotted closed circle are left parenthesis 2 comma 0 right parenthesis. An upward slanting arrow extends from the plotted point and passes through left parenthesis 8 comma 90 right parenthesis.

A. A coordinate plane shows the x-axis, labeled as Number of Minutes, ranging from 0 to 10 in increments of 1, and the y-axis, labeled as Number of Meters, ranging from 0 to 1600 in increments of 100. A curve with a closed circle at both the ends is shown. The coordinates of a plotted closed circle are left parenthesis 0 comma 0 right parenthesis. An upward curve extends from this point and increases steeply to left parenthesis 4 comma 900 right parenthesis, then levels off slightly, and then increases steeply to left parenthesis 7 comma 1500 right parenthesis.
