I've done the y = equations but I don't know how to do this one.

Tems11 [23]

Consider the equation

$-10x-y=-20$

1) First row of the table

Set x=0 and solve as follows:

$\begin{gathered} -10(0)-y=-20 \\ \Rightarrow-y=-20 \\ \Rightarrow y=20 \end{gathered}$

The answer is y=20 and the pair x-y is (0,20)

2) Second row

Set x=1 and solve, as follows:

$\begin{gathered} -10(1)-y=-20 \\ \Rightarrow-10-y=-20 \\ \Rightarrow-y=-10 \\ \Rightarrow y=10 \end{gathered}$

The answers are y=10 and (1,10)

3) Third row.

Set y=0 and solve as follows:

$\begin{gathered} -10x-(0)=-20 \\ \Rightarrow-10x=-20 \\ \Rightarrow x=\frac{20}{10}=2 \\ \Rightarrow x=2 \end{gathered}$

The answers are x=2 and (2,0)
