Since we have to solve this system graphically, we'll have to draw both lines.
To draw a line, simply build a little tables with two x,y values: for the first line we have

So, you can draw the points (0,3) and (1,2), connect them, and you'll have the graph of the line 
For the second line we have

So, you can draw the points (0,5) and (1,6), connect them, and you'll have the graph of the line 
Finally, we have to check where the two lines cross. If your drawing is accurate enough, you'll see that the point you're looking for is (-1, 4)
I’m think the angles are supplementary and you just have to find the value for each angle that is going to equal 180 degrees
M5+M7+81= 180
I’m not really sure just because I didn’t really get to really look at that well this is my guess??
