Question

A coordinate plane with four quadrants shows the x-axis ranging from negative 11 to 5 in increments of 1 and the y-axis from 3 to negative 16 in increments of 1. Points upper A, upper B, upper A prime, and upper B prime are plotted on quadrant 3. The plotted points are as follows: Upper A is left parenthesis negative 1 comma negative 3 right parenthesis and upper B is left parenthesis negative 3 comma negative 5 right parenthesis. The points are joined by a line. Upper A prime is plotted as left parenthesis negative 3 comma negative 9 right parenthesis and upper B prime as left parenthesis negative 9 comma negative 15 right parenthesis. The points are joined by a line.
