Question 59499: Can someone help me solve the system by graphing it for me?
I have to send it through the computer.
x - 2y = 8
x + y = -1
Thank you so much,
Lyn

You can put this solution on YOUR website! Hi Lyn,
E1) x - 2y = 8
E2) x + y = -1
:
For E1, let x=0 and solve for y
0-2y=8
-2y/-2=8/-2
y=-4 Plot (0,-4)
Now let y=0 and solve for x:
x-2(0)=8
x-0=8
x=8 Plot (8,0)
Connect the points and you have a line:
For E2, let x=0 and solve for y:
0+y=-1
y=-1 Plot (0,-1)
Now let y=0 and solve for x:
x+(0)=-1
x=-1 Plot (-1,0)
Connect the points and you have a second line:
They intersect at (2,-3)
I think I did this one earlier today.
Happy Calculating, Lyn!!!
