Question 1014722
{{{x-y=3}}}
{{{y=x-3}}}
So now you have a formula for the dependent variable y given the independent variable x.
It's the equation of a line so choose two values of x and get two data points.
Then graph.
When {{{x=0}}}, {{{y=0-3=-3}}}
(0,-3)
When {{{x=3}}}, {{{y=3-3=0}}}
(3,0)
Graph it.
