one easy way is first solve for y
3x-5y=9
minus 3x both sides
-5y=-3x+9
divide both sides by -5
y=\(\frac{3x-9}{5}\)
so
if x=-1
y=\(\frac{3(-1)-9}{5}\)
y=\(\frac{-3-9}{5}\)
y=\(\frac{-12}{5}\)
if x=0
y=\(\frac{3(0)-9}{5}\)
y=\(\frac{0-9}{5}\)
y=\(\frac{-9}{5}\)
if x=1
y=\(\frac{3(1)-9}{5}\)
y=\(\frac{3-9}{5}\)
y=\(\frac{-6}{5}\)
