Graph A.....parallel lines will have no solution because they never intersect
Here, z = kx
k = z/x
k = 228/12
k = 19
So, when x = 18,
z = 19 * 18
z = 342
In short, Your Answer would be: 342
Hope this helps!
Every degree is a touching point since each root factor is an x intercept
therefor the answer is 8th degree
