Question 59501
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.
{{{graph(300,200,-10,10,-10,10,(-x+8)/-2)}}}
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:
{{{graph(300,200,-10,10,-10,10,(-x+8)/-2,-x-1)}}}
They intercect at (2,-3)
Happy Calculating, Lyn!!!
