Answer:
Option D, x = 4
Step-by-step explanation:
Option A: y = 4 doesn't work because that line would be horizontal
Option B: y = 4x doesn't work because that would be diagnol
Option C: x = -4 doesn't work because that would a vertical line at -4
<em>Option D: x = 4 works because that would a vertical line at 4</em>
<em />
Answer: Option D, x = 4
No, he is not correct. The lines are the same, so there are an infinite number of solutions.
When two lines are parallel, then the solution is empty set.
It would be: 30/42 = 15/21 = 5/7
In short, Your Answer would be 5/7
Hope this helps!
