Which ordered pair is a solution of the equation y = x - 4?
A. (2,6)
B. (6,2)
C. (-2,6)
D. (-6,2)
Have you considered trying each point in the given equation
e.g. using (2,6)
LS = 6
RS = 2(6) - 4 = 8, nope!
(6,2)
LS = ...
RS= ...
etc
Anyone?
Tysm
thank you @mathhelper
what's the answer tho?
To determine which ordered pair is a solution to the equation y = x - 4, we need to substitute the values of x and y in the equation to see if it holds true.
Let's go through each option:
A. (2,6):
Plugging in x = 2 and y = 6 into the equation y = x - 4:
6 = 2 - 4
6 = -2
The equation does not hold true, so this option is not a solution.
B. (6,2):
Plugging in x = 6 and y = 2 into the equation y = x - 4:
2 = 6 - 4
2 = 2
The equation holds true, so this option is a solution.
C. (-2,6):
Plugging in x = -2 and y = 6 into the equation y = x - 4:
6 = -2 - 4
6 = -6
The equation does not hold true, so this option is not a solution.
D. (-6,2):
Plugging in x = -6 and y = 2 into the equation y = x - 4:
2 = -6 - 4
2 = -10
The equation does not hold true, so this option is not a solution.
Therefore, the only ordered pair that is a solution to the equation y = x - 4 is option B: (6,2).
