y=2X+2
y=mX+b
b = y intercept. This means the intercept of this graph is 2. plot a point at (0,2) this is where the graph starts
m = slope. so the slope of this line is 2. start at the point (0,2) and count up 2 units, over 1. up two, over one.
then connect the dots, and there ya go! :)

You can do the equation Y 2x plus 3 on a graph. On this graph the Y would equal 5 and X would equal to 0.
8
2x+3x = 5x
If 5 x equals 9 plus 2x then x equals?
Interpreting that function as y=x2+2x+1, the graph of this function would be a parabola that opens upward. It would be equivalent to y=(x+1)2. Its vertex would be at (-1,0) and this vertex would be the parabola's only zero.
