Which equation represents the line passing through (5,−2)(5, -2) and parallel to the y-axis?

A

x=5x = 5

B

y=−2y = -2

C

y=5y = 5

D

x=−2x = -2

Correct Answer: A

Choice A is the correct answer. Parallel to y-axis means vertical.

  1. Direction: Parallel to y-axis →\rightarrow Vertical line.
  2. Form: x=kx = k.
  3. Value: x-coordinate is 5.
  4. Equation: x=5x = 5.

💡 Strategic Tip: Parallel to Y →\rightarrow X equals. Parallel to X →\rightarrow Y equals.

Choice B is incorrect because it is horizontal (parallel to x-axis). Choice C is incorrect because wrong variable and value. Choice D is incorrect because wrong value.
