Determine which ordered pair is not a solution of y=-5x-4.
(10,-52)
(7,-39)
(-7,31)
(8,-44)
I think it is (7,-39)
( 10 , - 52 )
Becouse :
For x = 10
y = - 5 x - 4 = - 5 * 10 - 4 = - 50 - 4 = - 54
To determine which ordered pair is not a solution of the equation y = -5x - 4, you need to substitute the x and y values into the equation and check if it is true or false.
Let's go through each ordered pair:
1. For (10, -52):
Substituting x = 10 and y = -52 into the equation, we get:
-52 = -5(10) - 4
-52 = -50 - 4
-52 = -54
This equation is false, so (10, -52) is not a solution.
2. For (7, -39):
Substituting x = 7 and y = -39 into the equation, we get:
-39 = -5(7) - 4
-39 = -35 - 4
-39 = -39
This equation is true, so (7, -39) is a solution.
3. For (-7, 31):
Substituting x = -7 and y = 31 into the equation, we get:
31 = -5(-7) - 4
31 = 35 - 4
31 = 31
This equation is true, so (-7, 31) is a solution.
4. For (8, -44):
Substituting x = 8 and y = -44 into the equation, we get:
-44 = -5(8) - 4
-44 = -40 - 4
-44 = -44
This equation is true, so (8, -44) is a solution.
Based on our calculations, the ordered pair that is not a solution of y = -5x - 4 is (10, -52), not (7, -39).
