You can put this solution on YOUR website! Hi Lyn,
Can someone help me solve the system by graphing it for me?
I have to send it through the computer.
L1) x - 2y = 8
L2) x + y = -1
For L1, let y=0 and solve for x
x-2(0)=8
x-0=8
x=8 Plot (8,0)
Now let x=0 and solve for y:
0-2y=8
-2y/-2=8/-2
y=-4 plot (0,-4)
Connect the points and you have this line.
For L2), let y=0 and solve for x
x+0=-1
x=-1 Plot (-1,0)
Let x=0 and solve for y
0+y=-1
y=-1 Plot (0,-1)
Connect the points and you have a second line:
They intercect at (2,-3)
Happy Calculating, Lyn!!!
