Which graph represents a line with a slope of 0 and a y-intercept of -2?

A

Horizontal line at y = -2

B

Vertical line at x = -2

C

Line passing through origin with slope -2

D

Horizontal line at y = 2

Correct Answer: A

Choice A is the correct answer. Slope 0 means horizontal.

  1. Slope 0: Horizontal line.
  2. Intercept -2: Passes through (0,−2)(0, -2).
  3. Result: Horizontal line at y=−2y = -2.

💡 Strategic Tip: A zero-slope line is flat like the horizon.

Choice B is incorrect because it has undefined slope. Choice C is incorrect because it has slope -2. Choice D is incorrect because it is at the wrong height.
