The graph for the linear equation "y=x+2" is a straight line.

To draw the graph, you just need 2 points. 

You can take arbitrary values for "x" to find "y" and then draw the line.

For example, for x = 0 we have

y = 0 + 2

y = 2

So, one point is (0, 2)

For x = 1 we have

y = 1 + 2

y = 3

Another point is (1, 3)
