: Can someone help me on this problem?
I need to solve the following systems by graphing:
I have a x-axis and a y-axis .
x - 2y = 8
3x - 2y = 12

Can someone do the graph on the computer since I have to send it on the computer and can't use paper. (only 2 weeks left on this course)
I sure could use your help.
Thanks,

Hi Sher,
Hang in there, it's only 2 weeks.
Solve the following systems by graphing:
L1) x - 2y = 8
L2) 3x - 2y = 12

For L1) let x=0 and solve for y:
0-2y=8
-2y/8
-2y/-2=8/-2
y=-4
Plot (0,-4)
Now let y=0 and solve for x:
x-2(0)=8
x=8
Plot (8,0)
Connect the points and you have this line:

For L2) Let x=0 and solve for y
3(0)-2y=12
-2y=12
-2y/-2=12/-2
y=-6
Plot (0,-6)
Now let y=0 and solve for x:
3x-2(0)=12
3x=12
3x/3=12/3
x=4
Plot (4,0)
Connect the points and you have a second line like this:

The intersect at the solution(2,-3)
Happy Calculating, Sher!!!
