The graph is attached.

Work Step by Step

First, plot the two points on the coordinate plane, and then draw a line through both. If the line goes down from left to right, the slope is negative. If the line goes up from left to right, the slope is positive. If the line does not change in y value from left to right, the slope is 0. Using this information, it becomes clear that the slope is negative.
