Which ordered pair is a solution of y = x - 4?
A. (-1, -5)
B. (0, -3)
C. (2, 6)**
D. (3, 1)
Remember (x,y)
2 - 4 = 6 no way
Just plug in the numbers and do trial and error. See which ones work.
Yes
-5 = -1 -4
To determine which ordered pair is a solution of the equation y = x - 4, you need to substitute the given values of x and y and check if the equation holds true. Let's go through each option:
A. (-1, -5)
Substituting x = -1 and y = -5 in the equation, we have -5 = -1 - 4. Simplifying, we get -5 = -5. Therefore, (-1, -5) is a solution of the equation.
B. (0, -3)
Substituting x = 0 and y = -3 in the equation, we have -3 = 0 - 4. Simplifying, we get -3 = -4. Therefore, (0, -3) is not a solution of the equation.
C. (2, 6)
Substituting x = 2 and y = 6 in the equation, we have 6 = 2 - 4. Simplifying, we get 6 = -2. Therefore, (2, 6) is not a solution of the equation.
D. (3, 1)
Substituting x = 3 and y = 1 in the equation, we have 1 = 3 - 4. Simplifying, we get 1 = -1. Therefore, (3, 1) is not a solution of the equation.
Based on the above analysis, the ordered pair that is a solution of y = x - 4 is A. (-1, -5).
