Observing the given graph, we can see that the line passes through the points J(-2,3) and K(3,-2). One way to use a graph to find the slope of a line is to count out the change in x and y.
We can see that as the graph travels from left to right, the rise, or change in y, is -5. Similarly, the run, or change in x, is 5.
slope=runrise⇔m=5-5=-1
We can confirm this answer by using the other method, the Slope Formula.
m=x2−x1y2−y1
We will use the given points to solve for the slope.
