Practice makes perfect
We want to use the given equation to complete the table. This means that we need to substitute 17, 14, 11, 8 and 5 for a in the equation to get the value of the dependent variable b. Let's start with 17.
Now, let's do the same for the other values of the independent variable a, 14, 11, 8 and 5.
& b=14/2-2 → b= 5 [2mm]
& b=11/2-2 → b= 3.5 [2mm]
& b=8/2-2 → b= 2 [2mm]
& b=5/2-2 → b= 0.5
Finally, we complete the table.
