Determine which ordered pair is not a solution of
y=-5x-4.
A (10, -52)
B (7, -39)
C (-7, 31)
D (8, -44)
I'm thinking its A but I'm not 100% sure
looks good
To determine whether an ordered pair is a solution to a given equation, substitute the values of x and y into the equation and check if both sides of the equation are equal. Let's check each option:
A) Substituting x = 10 and y = -52 into the equation y = -5x - 4:
-52 = -5(10) - 4
-52 = -50 - 4
-52 = -54
Since -52 is not equal to -54, the ordered pair (10, -52) is not a solution.
B) Substituting x = 7 and y = -39 into the equation:
-39 = -5(7) - 4
-39 = -35 - 4
-39 = -39
Since -39 is equal to -39, the ordered pair (7, -39) is a solution.
C) Substituting x = -7 and y = 31 into the equation:
31 = -5(-7) - 4
31 = 35 - 4
31 = 31
Since 31 is equal to 31, the ordered pair (-7, 31) is a solution.
D) Substituting x = 8 and y = -44 into the equation:
-44 = -5(8) - 4
-44 = -40 - 4
-44 = -44
Since -44 is equal to -44, the ordered pair (8, -44) is a solution.
Therefore, the option that is not a solution is A) (10, -52).
