Plug in a value for one variable. Then it will give you the value for the other variable.
For example, the function rule is:
y = 2x + 3
Find the value of y for all whole number values of x from 5 to 7.
If x = 5, then y = 2*5+3 = 10 + 3 = 13
If x = 6, then y = 2*6+3 = 12 + 3 = 15
If x = 7, then y = 2*7+3 = 14 + 3 = 17
