Question 736458: Can you please help me solve and graph y=x-2? It has been a very long time since I have done this and I am lost.
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! solve and graph y=x-2
================
It is solved for y.
You can solve for x: x = y+2
--------------
It's 1 equation in 2 variables, --> an infinite # of solutions.
y = x-2
You can pick any number for x and find y.
----
To graph it, you need 2 points.
Pick 2 values for x and find y.
x = 0, y = -2 --> point (0,-2)
x = 2, y = 0 --> point (2,0)
x = 100, y = 98 --> (100,98)
------
Plot at least 2 points, draw a line thru them.
Every point on the line is a "solution."
