Work Step by Step

To graph an equation, start at a given point. Here, plug in 0 for x and 0 for y, which will give you a point. Next, use the slope given in the equation to find another point. For example, if the slope is 2/3, then move three units to the right, and then move two units up. Mark that point, and then connect them using a line. Do this for both of the equations, and find where the equations intersect. When we do this for this problem, we find that the intersection is: (3,9)
