First solve the linear system.
Solved by pluggable solver: Linear System solver (using determinant)
Solve:
+system%28+%0D%0A++++1%5Cx+%2B+1%5Cy+=+-1%2C%0D%0A++++3%5Cx+%2B+-1%5Cy+=+-5+%29%0D%0A++

Any system of equations:


has solution

or



(x=-1.5, y=0.5}


Then plot your graph
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+x%2By=1%2C+3x-y=-5%29+
