determine which ordered pair is not a solution of y = -5x -4
(10, -52)
(7,-39)
(-7, 31)
(8,-44)
Try each of them
for example
-52 = -5(10) - 4
-52 = -54 I do not think so
check the others as well.
what will it be??
To determine which ordered pair is not a solution of the equation y = -5x - 4, you need to substitute the x and y values of each ordered pair into the equation and see if the equation holds true.
Let's go through each ordered pair one by one:
1. For the first ordered pair (10, -52), substitute 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 first ordered pair (10, -52) is not a solution of the equation.
2. For the second ordered pair (7, -39), substitute x = 7 and y = -39 into the equation:
y = -5x - 4
-39 = -5(7) - 4
-39 = -35 - 4
-39 = -39
Since -39 is equal to -39, the second ordered pair (7, -39) is a solution of the equation.
3. For the third ordered pair (-7, 31), substitute x = -7 and y = 31 into the equation:
y = -5x - 4
31 = -5(-7) - 4
31 = 35 - 4
31 = 31
Since 31 is equal to 31, the third ordered pair (-7, 31) is a solution of the equation.
4. For the fourth ordered pair (8, -44), substitute x = 8 and y = -44 into the equation:
y = -5x - 4
-44 = -5(8) - 4
-44 = -40 - 4
-44 = -44
Since -44 is equal to -44, the fourth ordered pair (8, -44) is a solution of the equation.
Therefore, the ordered pair that is not a solution of y = -5x - 4 is (10, -52).
