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.

Answer:
The answer to your question is the first option
Step-by-step explanation:
Process
1.- Find the slope of the original line
y =
slope = m =
2.- Find the slope of the perpendicular line
slope = 3
3.- Find the line of the new equation
y - y1 = m (x - x1)
y - 5 = 3 (x + 1)
