We start by plotting the point of the y-intercept. The graph passes through (0, -2); this is on the y-axis, so this is the y-intercept.
From here we use the slope to find the next point. Slope is rise/run. Since our slope is -2/3, this means from our y-intercept, we go down 2 and over to the right 3 and plot our next point. We then draw a line between the two points.
