If you have all the answers to the whole test that would be amazing. 22 questions.
Asking to cheat?
You'll be on the banned list if you continue like this. =(
if you cannot plug in the values and evaluate the expression, you are in deep trouble.
For example, is (5,3) a solution?
-4(5)-9 = -29
Nope, not equal to 3.
To determine which ordered pair is not a solution of the equation y = -4x - 9, we need to substitute the values of x and y for each ordered pair into the equation and see if it holds true.
Let's check each ordered pair:
1. (-9,27):
Substituting x = -9 and y = 27 into the equation, we get:
27 = -4(-9) - 9
27 = 36 - 9
27 = 27
Since the equation holds true, the ordered pair (-9,27) is a solution.
2. (3,-21):
Substituting x = 3 and y = -21 into the equation, we get:
-21 = -4(3) - 9
-21 = -12 - 9
-21 = -21
The equation holds true, so (3,-21) is a solution.
3. (-6,15):
Substituting x = -6 and y = 15 into the equation, we get:
15 = -4(-6) - 9
15 = 24 - 9
15 = 15
The equation holds true, so (-6,15) is a solution.
4. (5,-28):
Substituting x = 5 and y = -28 into the equation, we get:
-28 = -4(5) - 9
-28 = -20 - 9
-28 = -29
Since the equation does not hold true, the ordered pair (5,-28) is not a solution.
Therefore, the ordered pair (5,-28) is not a solution of the equation y = -4x - 9.
