Which ordered pair is not a solution of
y = 4x -9
(-9, 27)
(3, -21)
(-6, 15)I think this one?
(5, -28)
Nope. Are you certain you have the right set of answers to the question? I don't see that any are in the solution set.
when x=5, y=-9
when x=-6, y=large negative
when x=3, y=3
when x=-9, y=large negative.
let me check
nope its all correct
All of them are NOT a solution
No solution. Duh
To determine which ordered pair is not a solution of the equation y = 4x - 9, we need to substitute the x and y values of each pair into the equation and check if they satisfy the equation.
Let's go through each ordered pair one by one:
1. (-9, 27):
Substituting x = -9 and y = 27 into the equation:
27 = 4(-9) - 9
27 = -36 - 9
27 = -45
The equation is not satisfied, so (-9, 27) is not a solution.
2. (3, -21):
Substituting x = 3 and y = -21 into the equation:
-21 = 4(3) - 9
-21 = 12 - 9
-21 = 3
The equation is not satisfied, so (3, -21) is not a solution.
3. (-6, 15):
Substituting x = -6 and y = 15 into the equation:
15 = 4(-6) - 9
15 = -24 - 9
15 = -33
The equation is not satisfied, so (-6, 15) is not a solution.
4. (5, -28):
Substituting x = 5 and y = -28 into the equation:
-28 = 4(5) - 9
-28 = 20 - 9
-28 = 11
The equation is not satisfied, so (5, -28) is not a solution.
Therefore, the correct answer is (5, -28).
