C.
Line passing through origin with slope -2
D.
Horizontal line at y = 2
Detailed Explanation
Choice A is correct. Choice A is the correct answer. Slope 0 means horizontal. 1. Slope 0: Horizontal line. 2. Intercept -2: Passes through . 3. Result: Horizontal line at . 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.
Key Steps:
•
The correct answer is Horizontal line at y = -2
Why others are wrong:
