You can put this solution on YOUR website!
the two equations to graph are
y = -x -2
y = 5x +40
red line is first equation and green line is second equation
+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+-x-2%2C+5x+%2B40%29+
from the graph, we see that (-7, 5) is the point of intersection of the two lines
