Question 1046090
-3x-y=10
 4x-4y=8
or
y = -3x - 10 
P(0,-10) and P(-2, -4) on this line:  Plot and connect with the Line.
y = x - 2
P(0, -2) and (2,0) on this line:    Plot and connect with the Line.
P(-2,-4) is the ordered pair that is the solution for this system of EQs
On may CHECK by substituting x= -2 and y = -4 into the EQs of these Lines
