4-34.

Copy this table and use your pattern skills to complete it.

 IN ($x$) $2$ $10$ $−3$ $x$ OUT ($y$) $4$ $28$ $13$ $−17$ $10$ $2.5$ $148$ $3x − 2$

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 $2$.

 IN ($x$) $2$ $10$ $−3$ $x$ OUT ($y$) $4$ $28$ $13$ $−17$ $10$ $2.5$ $148$ $3x − 2$

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

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