Give a geometric description of the following systems of equations.

Select Answer Two parallel lines Two lines that are the same Two lines intersecting in a point  1. $\left\lbrace\begin{array}{rrrrrr}& -6 \, x&- &3 \,y&=&-15\\& -10 \, x&- &5 \,y&=&-25\\ \end{array}\right.$

Select Answer Two parallel lines Two lines that are the same Two lines intersecting in a point  2. $\left\lbrace\begin{array}{rrrrrr}& 7 \,x&- &5 \,y&=&7\\& -6 \, x&+& 5 \, y&=&7\\ \end{array}\right.$

Select Answer Two parallel lines Two lines that are the same Two lines intersecting in a point  3. $\left\lbrace\begin{array}{rrrrrr}& -6 \, x&- &3 \,y&=&-15\\& -10 \, x&- &5 \,y&=&-27\\ \end{array}\right.$
