Answer:

C.) This system has infinitely many solutions.

Explanation:

y = 2x - 4

2x - y - 4 = 0

2x - y - 4 = 0 can be rewritten as y = 2x - 4 as shown below

2x - y - 4 = 0

-y = -2x + 4

-y/-1 = -2x/-1 + 4/-1

y = 2x - 4

y = 2x - 4 is equal to 2x - y - 4 = 0 because the slope is both 2 and both its y-intercept is -4, these two are coincidence, as they call it, meaning these two lines are the same, so its solutions are anywhere on its line. Shown below in a graph.
