determine which of the following ordered pairs is a solution to the equation 3x-8=-4y . (0,2) (1,1) (-1,1) (0,-2)

1 answer

To determine which of the given ordered pairs is a solution to the equation \( 3x - 8 = -4y \), we will substitute \( x \) and \( y \) values from each pair into the equation.

  1. For the ordered pair \( (0, 2) \): \[ 3(0) - 8 = -4(2) \ -8 = -8 \quad \text{(True)} \]

  2. For the ordered pair \( (1, 1) \): \[ 3(1) - 8 = -4(1) \ 3 - 8 = -4 \ -5 = -4 \quad \text{(False)} \]

  3. For the ordered pair \( (-1, 1) \): \[ 3(-1) - 8 = -4(1) \ -3 - 8 = -4 \ -11 = -4 \quad \text{(False)} \]

  4. For the ordered pair \( (0, -2) \): \[ 3(0) - 8 = -4(-2) \ -8 = 8 \quad \text{(False)} \]

So, the only ordered pair that is a solution to the equation \( 3x - 8 = -4y \) is (0, 2).
