You can put this solution on YOUR website! How do I graph 2x-2y=4 and y-x=6?
basically you make 2 tables 1 for each equation
2x-2y=4
x|y
2|0 if x=2 2(2)-2y=4=> 4-2y=4=> -2y=0 then y=0 (2,0)
4|2 if x=4 2(4)-2y=4=> 8-2y=4=> -2y=-4 then y=2 (4,2)
6|4 if x=6 2(6)-2y=4=> 12-2y=4=> -2y=-8 then y=4 (6,4)
Plot the points to make the graph
Next one
y-x=6
x|y
1|7 if x=1 y-(1)=6 then y=7 (1,7)
2|8 if x=2 y-(2)=6 then y=8 (2,8)
3|9 if x=3 y-(3)=6 then y=9 (3,9)
Plot the points to make the graph
