Problem given
3x+7y=-63. x-y=-1. Solve each system of equations by graphing. Clearly identify your solution.
Solution
For this case we can plot the two equations and we got:
After see the plot we can see that the solution for this case is :
x= -7 and y= -6
If we convert into the standard form y=mx+b we have:
7y=-63-3x
y= -9 -3/7 x
x-y=-1
y= x+1
