    There are a number of ways this can be done...

    since the slope is defined as m=\frac{\Delta y}{\Delta x}=\frac{\text{rise}}{\text{run}}, and the slope given to us is m=\frac{3}{2}, we see that from a given point on the line, we can increase the y value by three and increase the x value by two.

    So one additional point could be (3+3,-1+3)=(6,2)

    Also, note that \frac{3}{2}=\frac{-3}{-2}

    So we can subtract three from a y value of a point on the line, and subtract 2 from the x value of a point on the line.

    So using the original point given to you, we see another possible point could be (3-3,-1-2)=(0,-3)

    I leave it for you to find another possible point on the line.

    I hope this makes sense!
