Determine which of the following ordered pairs is a solution to the equation 3x - 8 = -4y.

A: (0, -2)

B: ( -1, 1)

C: (1,1)

D: (0,2 )

1 answer

To determine which ordered pairs satisfy the equation \( 3x - 8 = -4y \), we need to substitute the \( x \) and \( y \) values from each ordered pair into the equation and see if it holds true.

A: (0, -2)

Substituting \( x = 0 \) and \( y = -2 \): \[ 3(0) - 8 = -4(-2) \ -8 = 8 \quad \text{(False)} \]

B: (-1, 1)

Substituting \( x = -1 \) and \( y = 1 \): \[ 3(-1) - 8 = -4(1) \ -3 - 8 = -4 \ -11 = -4 \quad \text{(False)} \]

C: (1, 1)

Substituting \( x = 1 \) and \( y = 1 \): \[ 3(1) - 8 = -4(1) \ 3 - 8 = -4 \ -5 = -4 \quad \text{(False)} \]

D: (0, 2)

Substituting \( x = 0 \) and \( y = 2 \): \[ 3(0) - 8 = -4(2) \ -8 = -8 \quad \text{(True)} \]

The only ordered pair that satisfies the equation \( 3x - 8 = -4y \) is D: (0, 2).
