Convert y=−25x+2y = -\frac{2}{5}x + 2 to standard form.

A

2x+5y=102x + 5y = 10

B

2x+5y=22x + 5y = 2

C

5x+2y=105x + 2y = 10

D

2x−5y=102x - 5y = 10

Correct Answer: A

Choice A is the correct answer. Clear fraction.

  1. Multiply by 5: 5y=−2x+105y = -2x + 10.
  2. Add 2x: 2x+5y=102x + 5y = 10.

💡 Strategic Tip: Multiply by the denominator first.

Choice B is incorrect because didn't multiply the constant. Choice C is incorrect because swapped coefficients. Choice D is incorrect because sign error.
