Answers to the Extended Problems are below in random order.
\(\begin{align}&x+y=-1\ & \ \ \ \ &y+3=-\frac{1}{2}(x-7)\ & \ \ \ \ &y=\frac{3}{4}x+\frac{11}{2}\\\\
&4x-2y=-1\ & \ \ \ \ &-\frac{15}{4}\ & \ \ \ \ &y=-2x\end{align}\)
\(\begin{align}
& a\parallel c\ & \ \ & \text{because they have the same slope} \\
& a\bot b \ & \ & \text{because they have opposite reciprocal slopes}\\
& b\bot c \ & \ & \text{because they have opposite reciprocal slopes}\\
\end{align}\)
Jane should approximately charge between \(\$10,909\) and \(\$11,663\) depending on whether she uses the year or millage (or a combination of the two) to determine her selling price. Don't forget to justify your reasoning for your selling price.
\(3x+2y=-4\)
