Math Problem Statement

Which ordered pairs represent points on the graph of this equation? Select all that apply for the equation y = (1/3)x.

Solution

The given equation is y=13xy = \frac{1}{3}x. To determine which ordered pairs satisfy this equation, we will substitute the xx-value of each pair into the equation and see if the resulting yy-value matches.

Verification:

  1. For (6,2)(-6, -2): y=13(6)=2y = \frac{1}{3}(-6) = -2 This is correct.

  2. For (6,5)(-6, 5): y=13(6)=25y = \frac{1}{3}(-6) = -2 \neq 5 This is incorrect.

  3. For (6,2)(6, 2): y=13(6)=2y = \frac{1}{3}(6) = 2 This is correct.

  4. For (3,1)(3, 1): y=13(3)=1y = \frac{1}{3}(3) = 1 This is correct.

  5. For (0,0)(0, 0): y=13(0)=0y = \frac{1}{3}(0) = 0 This is correct.

  6. For (3,1)(-3, -1): y=13(3)=1y = \frac{1}{3}(-3) = -1 This is correct.

Correct Answers:

  • (6,2)(-6, -2)
  • (6,2)(6, 2)
  • (3,1)(3, 1)
  • (0,0)(0, 0)
  • (3,1)(-3, -1)
