Question 672815
1.) y = x^2 - 1 2.) y = 5/2x - 3 3.) 2y = 4x + 8 4.) y = 2x^2 - 6 These are all graphing equations.
----------------
#2 & #3 are linear, so you need 2 points.
---------
y = 5/2x - 3
Pick 2 values for x and find y
Plot the 2 points, draw a line thru them.
=================
 3.) 2y = 4x + 8
y = 2x+4
Same as #2
--------------
The other 2 are 2nd order.
Plot as many points as you like, then draw a smooth curve thru them.
