[SOLVED] need a little help graphing some linear equations please!

The following pair of equations came with the instruction:

Solve by graphing.

2x+y=5

3x-y=10

I have solved questions like this before, however, this one proved rather hard so I put it into microsoft math and came out with these coordinates for the equations:

2x+y=5

(2,1) (4,-3)

3x-y=10

(1,-7) (2,-4)

I tried to work it out like this:

If 2x+y=5 then

y=5-2x

If:

x=0 y=5

x=1 y=3

x=2 y=1

x=3 y=-1

---------

If 3x-y=10 then

y=10-3x

If:

x=0 y=10

x=1 y=7

x=2 y=4

x=3 y=1

Is my working correct?

I think it is, but it never hurts to make sure.

Thanks in advance for your help!
