Solve: 2x3y>62x - 3y > 6 for yy.

A

y<23x2y < \frac{2}{3}x - 2

B

y>23x2y > \frac{2}{3}x - 2

C

y<23x+2y < \frac{2}{3}x + 2

D

y>23x+2y > \frac{2}{3}x + 2

Correct Answer: A

Choice A is the correct answer. Isolate yy and watch the sign.

  1. Subtract 2x: 3y>2x+6-3y > -2x + 6
  2. Divide by -3: y<23x+63y < \frac{-2}{-3}x + \frac{6}{-3} (Reverse sign!)
  3. Simplify: y<23x2y < \frac{2}{3}x - 2

?�� Strategic Tip: Dividing by negative coefficient of yy flips the inequality.

Choice B is incorrect because it fails to reverse the sign. Choice C is incorrect because it has the wrong y-intercept sign. Choice D is incorrect because it fails to reverse sign and has wrong intercept.
