Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
use y=2x+1 on a graph, find the variable y or x.
-------------
You need two points to graph a line:
If x = 0 y = 2*0+1 = 1
If x = 2 y = 2*2+1 = 5
------------------------
Plot those two points: (0,1) and (2,5)
and draw a line thru them.
That is the graph you want.
