solve each of the given systems by sketching the lines represented by each equation in the system, then determining the coordinates of the point of intersection. Each of these problems have been designed so that the coordinates of the intersection point are integers. Check your solution. 

Please show the work done to get the points used to sketch each of the lines.

x − 2y = −4

y = (5 /2) x + 6
