You can put this solution on YOUR website!
x-y=-3...or...x+3=y...or...y=x+3..NOW
SEE THIS AND YOU SHOULD BE ABLE TO DO BY YOUR SELF
y=5-x
y=-1
y=4-3x
x=3y
x-y=-3
to graph these eqns.,you have to find few points satisfying the above relations ,make a table and plot those points.generally we set different values for x arbitrarily say 0,1,2,-1,-2 etc.and find y from the given formula..see tables below for few of the eqns.
y=5-x
x...0...1...2...-1...-2
y...5...4...3...6....7...now plot these points on the graph to a suitable scale.see the graph below
+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+5-x%29+
*************
y=-1...note here that y is always -1 whatever may be x.
x....0....1....2....-1....-2
y....-1..-1...-1....-1....-1
let me show for variety another which is not listed by you
x=-2....note here that x is always -2 whatever may be the value of y
x....-2....-2....-2....-2....-2
y.....0.....1.....2....-1....-2
