To determine which of the following ordered pairs is a solution to the equation 3x - 8 = -4y, we need to substitute the values of x and y from each ordered pair into the equation and see if it is satisfied.
Option 1: (2, -2)
Substituting x = 2 and y = -2 into the equation, we have:
3(2) - 8 = -4(-2)
6 - 8 = 8
-2 = 8
This is not true, so (2, -2) is not a solution to the equation.
Option 2: (-4, 0)
Substituting x = -4 and y = 0 into the equation, we have:
3(-4) - 8 = -4(0)
-12 - 8 = 0
-20 = 0
This is not true, so (-4, 0) is not a solution to the equation.
Option 3: (5, 4)
Substituting x = 5 and y = 4 into the equation, we have:
3(5) - 8 = -4(4)
15 - 8 = -16
7 = -16
This is not true, so (5, 4) is not a solution to the equation.
Option 4: (6, -5)
Substituting x = 6 and y = -5 into the equation, we have:
3(6) - 8 = -4(-5)
18 - 8 = 20
10 = 20
This is not true, so (6, -5) is not a solution to the equation.
Thus, none of the given ordered pairs is a solution to the equation 3x - 8 = -4y.
Determine which of the following ordered pairs is a solution to the equation 3x - 8 = -4y
