Answer:
C.) This system has infinitely many solutions.
Step-by-step 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.
