SOLUTION: Hello, A while back, I was looking for help in figuring out the graphs below. I haven't gotten an answer yet. Graph the following: a) x+y=-3 2x-3y=4 b) x-y=3 2x+

Question 904954: Hello,
A while back, I was looking for help in figuring out the graphs below. I haven't gotten an answer yet.
Graph the following:
a) x+y=-3
2x-3y=4
b) x-y=3
2x+3y=-4
c) x+y=3
2x+3y=4
d) x+y=-3
2x-3y=-4

Not following the rules is a good reason not to get an answer
Here are the website rules.
Three simple Website rules
a) Limit 5 problems within 24 hours
b) No similar problems
c) Submit one problem one at a time once
Two is not one.
No similar problems
Similar means they are the same type problem but differ by the numbers or addition vs subtraction.
So you broke two of the three rules in one try. Too many problems and they are similar.
This suggests to us that you are not trying to learn but just want us to do your homework for you.
About 50% of the problems get answered.

a)

Solved by pluggable solver: Solve the System of Equations by Graphing

Start with the given system of equations:

In order to graph these equations, we need to solve for y for each equation.

So let's solve for y on the first equation

Start with the given equation

Subtract from both sides

Rearrange the equation

Divide both sides by

Break up the fraction

Reduce

Now lets graph (note: if you need help with graphing, check out this solver)

Graph of

So let's solve for y on the second equation

Start with the given equation

Subtract from both sides

Rearrange the equation

Divide both sides by

Break up the fraction

Reduce

Now lets add the graph of to our first plot to get:

Graph of (red) and (green)

From the graph, we can see that the two lines intersect at the point (,) (note: you might have to adjust the window to see the intersection)
