Solve for y:
Multiply both sides by -1:
[tex]\begin{gathered} -1(5x-y)=-1(-3) \\ y-5x=3 \end{gathered}[/tex]Add 5x to both sides:
[tex]\begin{gathered} y-5x+5x=3+5x \\ y=5x+3 \end{gathered}[/tex]Now, in order to graph the equation we need to find at least two points. In this case, let's evaluate the function for -2,-1,0,1,2:
