Graphing the Function f(x) = x + 2

I plotted 6 different points that satisfied the equation f(x) = x + 2 starting with 1 as the value of x.

The line would cross the y-axis at the point (0, 2) but this line segment does not show that because the first value of x that I plotted was 1. If I had started with -1 then the line segment would have crossed the y-axis. . . maybe next time!

This line segment is not steep but in between. It looks like it rises at a 45 degree angle. That makes sense because for every 1 increase in the value of x there is 1 increase in the value of f(x).
