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?
-$\left\{ \begin{aligned}
y - 2 x & = 3 \
6 y & = 12 x + 18
\end{aligned} \right.$
A)identical lines; infinite number of solutions
B)parallel lines; no solution
C)lines intersecting at a single point; one solution
