Which equation represents the same line as y=2x−5y = 2x - 5?

A

2x−y=52x - y = 5

B

2x+y=52x + y = 5

C

x−2y=5x - 2y = 5

D

2x−y=−52x - y = -5

Correct Answer: A

Choice A is the correct answer. Rearrange to Standard Form.

  1. Subtract y: 0=2x−y−50 = 2x - y - 5.
  2. Add 5: 5=2x−y5 = 2x - y.
  3. Rewrite: 2x−y=52x - y = 5.

💡 Strategic Tip: Move variables to one side, constants to the other.

Choice B is incorrect because sign error on y. Choice C is incorrect because coefficients swapped. Choice D is incorrect because sign error on constant.
