Worksheet Worksheet 4
1.
Describe the configuration of the following system of equations. If they intersect at a single point, determine the coordinates of that point.
\begin{equation*}
\left\{ \begin{array} {rcrcr}
2x \amp - \amp y \amp = \amp 7 \\
-x \amp + \amp 3y \amp = \amp -1
\end{array} \right.
\end{equation*}
2.
Describe the configuration of the following system of equations. If they intersect at a single point, determine the coordinates of that point.
\begin{equation*}
\left\{ \begin{array} {rcrcr}
x \amp + \amp 3y \amp = \amp 0 \\
2x \amp + \amp 5y \amp = \amp -1
\end{array} \right.
\end{equation*}
3.
