Find the slope of the line given by 4x−2y=104x - 2y = 10.

A

22

B

−2-2

C

44

D

12\frac{1}{2}

Correct Answer: A

Choice A is the correct answer. Convert to slope-intercept form.

  1. Subtract 4x: −2y=−4x+10-2y = -4x + 10
  2. Divide by -2: y=2x−5y = 2x - 5
  3. Slope: The coefficient of xx is 2.

💡 Strategic Tip: Shortcut: Slope m=−A/B=−4/(−2)=2m = -A/B = -4/(-2) = 2.

Choice B is incorrect because it misses the sign change. Choice C is incorrect because it ignores the coefficient of y. Choice D is incorrect because it flips the fraction.
