How do i plot the following 5 equations?
1.) y= x+2
2.) y=2x-2
3.) y=2x+4
4.) y=1/6+6
---------------
1 - 3 are linear, meaning the graph is a straight line.
Find 2 points, draw a line thru them.
Let x = any value, find y, plot the points.

#4 has no x ??

5.) y=1/2Xsq-8
#5 is ambiguous. It could be (1/2)x^2 - 8
or (1/(2x^2)) - 8 or something else.
