Question 354623: In my homework I need to graph linear systems and estimate the solution.
I'm not sure how to graph an equation.. I really need help.
One of my problems is..
-x + 6y = -12
x + 6y = 12
Found 2 solutions by Alan3354, stanbon:

You can put this solution on YOUR website! These are linear, straight lines.
Find 2 points and draw a line thru them.
----------
-x + 6y = -12
x = 12 - 6y
Pick 2 values for y and find x.
y = 0, x = 12 --> (12,0)
y = 2, x = 0 --> (0,12)
Plot the 2 points, draw a line thru them.
---------------
Do the same for the other equation.

---
Let x = 0, then y = -2 giving you point(0,-2)
Let y = 0, then x = 6 giving you point (6,0)
---
Plot those two points and draw a line thru them.
========================
x + 6y = 12
Let x = 0, then y = 2 giving you point (0,2)
Let y = 0, then x = 12 giving you point(12,0)
---
Plot those two points and draw a line thru them.
============
Find the intersection of the two lines:
============
Looks like (12,0)
