What is the y-intercept of the graph?
A) -2
B) 2
C) -4
D) 4

Parallel lines

Step-by-step explanation:

Line BC:

Line AD:

Adding both equations, in this case, gives us the point at which the lines intersect:

Since zero will never equal fourteen, the equation above means that lines BC and AD will never intersect. When two lines have no point in common, they are said to be parallel lines.
