-2x+3y=-9
Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Y=2x+1
-2x+3y=-9
---------------
y = 2x+1
y = (2/3)x - 3
---------------------
y=2x+1
If x = 0, y = 1
If x = 1, y = 3
Points: (0,1), (1,3)
Plot the points and draw a line thru them.
--------------------------
y = (2/3)x - 3
If x = 0, y = -3
If x = 3, y = -1
Points: (0,-3), (3,-1)
---------------------------

=====================
Solution: (-3,-5)
Cheers,
