Question 156575: These are two problems, that I do not get!
Your suppose to graph a line for both of them.
3x+2y=-6
and y=-3x-1 can you help me figure these out..thanks

You can put this solution on YOUR website! 3x+2y=-6
2Y=-3X-6
Y=-3X/2-6/2
Y=-3X/2-3 (RED LINE)
y=-3x-1 (GREEN LINE)
 (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions -3x/2 -3 and -3X -1).

------------------------
These are linear equations, meaning the graph is a straight line. All you need to graph a straight is 2 points. One way is to set x = 0 and find y, then y = 0 and find x.
--------------------
3x+2y=-6
3*0 + 2y = -6
y = -3
So the point is (0,-3)
Then y = 0:
3x = -6
x = -2
That point is (-2,0)
The line thru them extending forever in both directions, is the graph.
------------------
y=-3x-1
y=-1 --> (0,-1) one point
0=-3x-1
x = -1/3 --> (-1/3,0) 2nd point
Sometimes the 2 points will be so close together that you lose accuracy in the paper graph and it's better to find another point.
You can set x (or y) equal to any value and solve for the other.
---------------
Set x=5
y = -3*5 -1
y = -16 ---> (5,-16)
