Question 391980
Just make a chart with 2 columns, label the left column x and the right column y. Put in certain values for x, like this:

x       y
--------------
-2
-1
0
1
2


Then, find each value of y using the function y = x-2

x       y
--------------
-2      -4
-1      -3
0       -2
1       -1
2        0

Repeat the same process for the other chart.
