(A)Are the Graphs of the Equations Are $\left\{ \begin{array} { r } \frac { 1 } { 4 } x - y = 1 \\x = 4\end{array} \right.$

Multiple Choice

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?
- $\left\{ \begin{array} { r } \frac { 1 } { 4 } x - y = 1 \\x = 4\end{array} \right.$

A) parallel lines; no solution
B) lines intersecting at a single point; one solution
C) identical lines; infinite number of solutions
