Copy the table below onto your paper and use your pattern skills to complete it.

 IN $(x)$ in (x) column 1 $2$ in (x) column 2 $10$ in (x) column 3 $0$ in (x) column 4 $7$ in (x) column 5 $–3$ in (x) column 6 blank in (x) column 7 $–10$ in (x) column 8 $100$ in (x) column 9 $x$ OUT $(y)$ out (y) column 1 $–6$ out (y) column 2 $–30$ out (y) column 3 $0$ out (y) column 4 blank out (y) column 5 blank out (y) column 6 $15$ out (y) column 7 blank out (y) column 8 blank out (y) column 9 blank
1. Explain in words what is done to the input value, $x$, to produce the output value, $y$.

If you multiply $x$ by $-3$, you get $y$.

2. Write the process you described in part (a) in algebraic symbols.

$-3x=y$
