Question 82282
GRAPH each equation to find the solution of the system:
x-y=4
y = x-4
You need two points to sketch the line:
If x=0, y=-4
If x=4, y=0
Plot the two points and draw the line thru them.
---------------------------
2x+3y= -2 
3y=-2x-2
y = (-2/3)x - (2/3)
If x=0, y=-2/3
If x=3, y=-8/3
Plot the two points and draw the line thru them.

{{{graph(400,300,-10,10,-10,10,x-4,(-2/3)x-(2/3))}}}
