Without graphing, decide:
(a) Are the graphs of the equations are identical lines, parallel lines, or lines intersecting at a single point?
(b) How many solutions does the system have?
-$\left\{ \begin{array} { l }
5 x + y = - 12 \
2 x + 2 y = 0
\end{array} \right.$
A) lines intersecting at a single point; one solution
B) parallel lines; no solution
C) identical lines; infinite number of solutions

The Answer is A

Without Graphing, Decide: (A) Are the Graphs of the Equations {5x+y=−122x+2y=0\left\{ \begin{array} { l } 5 x + y = - 12 \\2 x + 2 y = 0\end{array} \right.{5x+y=−122x+2y=0​
