4-41.

On your paper, copy the table below and use your pattern skills to complete it.

 IN (x) OUT (y) $2$ $10$ $–3$ $x$ $4$ $28$ $13$ $–17$ $10$ $2.5$ $148$ $3x – 2$
1. Explain in words what is done to the input value, $x$, to produce the output value, $y$.

See the table above.

The equation is $y=3x−2$.

Multiply $x$ by $3$ and subtract $2$.

2. Explain the process you used to find the missing input values.

How did you use the equation to solve for $x$?
