Question 173692
3x+2y+4=0 graph this line
3x+2y = -4
------------
This is a straight line.  You can find 2 points and draw a line thru them.
The intercepts will work.  Set x = 0 and find y, then y=0 and find x.
@x=0, y = -2 --> (0,-2)
@y=0, x = -4/3 --> (-4/3, 0)
If the fraction is not convenient, set y = -5, then x = 2 --> (2,-5)
