See explanation

Explanation:

Consider first #y=x#

This means that whatever value you give to x ands up being the value of #y#.

#x# is positive so as you move from left to right the graph line goes upwards. Consequently for every 1 along the line has gone up 1 as well.

Now think about the #+2#

This has the effect of lifting the graph up by the value of 2.

Build a table of values. Plot the points and draw the line.
