Question 127875
Solve the system by graphing. 
x + 3y = -3
2x – y =  8
--------------
Solve each equation for "y".
y = (-1/3)x -1
y = 2x - 8
----------------
Plot points for each equation:
y = (-1/3)x - 1
If x = 0, y = -1
If x = 3, y = -2
Plot the points: (0,-1) and (3,-2)
and draw a line thru them.
------------------------------
y = 2x - 8
If x = 0, y = -8
If x = 1, y = -6
---------------------
plot the points: (0,-8) and (1,-6)
and draw a line thru them.
=============================
{{{graph(400,300,-10,10,-10,10,(-1/3)x-1, 2x-8)}}}
Solution: (3,-2)
