To find the first ordered pair put x=-15 in the equation to get:
[tex]y=\frac{1}{5}(-15)-1=-4[/tex]
So the first ordered pair is (-15,-4).
To find the second ordered pair, put y=-5 in the equation to get:
[tex]\begin{gathered} -5=\frac{1}{5}x-1 \\ -4=\frac{1}{5}x \\ x=-20 \end{gathered}[/tex]
So the second ordered pair is (-20,-5).
