Question

y = x + 4
y = x - 4
does this system have a solution?

Answer 1

Answer:

No solution

Step-by-step explanation:

y = x + 4

y = x - 4

The slopes are the same  (1), but the y intercepts are different ( 4, -4)

That means the lines are parallel, so they will not intersect.  That means the system does not have a solution.
