Which of the following is an ordered pair of the relation y = - 2/3x + 6?

(1 point)
• (1,4)
O -3)
(3,8)
(3, 4)

1 answer

To determine which of the options is an ordered pair in the relation represented by the equation \( y = -\frac{2}{3}x + 6 \), we can substitute the \( x \)-values from the ordered pairs into the equation and see if we get the corresponding \( y \)-value.

Let's check each option:

  1. For (1, 4): \[ y = -\frac{2}{3}(1) + 6 = -\frac{2}{3} + 6 = \frac{16}{3} \quad \text{(This is not 4)} \]

  2. For (-3, 3): \[ y = -\frac{2}{3}(-3) + 6 = 2 + 6 = 8 \quad \text{(This is not 3)} \]

  3. For (3, 8): \[ y = -\frac{2}{3}(3) + 6 = -2 + 6 = 4 \quad \text{(This is not 8)} \]

  4. For (3, 4): \[ y = -\frac{2}{3}(3) + 6 = -2 + 6 = 4 \quad \text{(This is correct)} \]

The correct ordered pair is (3, 4).
