Answer: No
The ordered pair (2,4) is not a solution to the equation y = x-2
=========================================================
Step-by-step explanation:
Any point is of the form (x,y)
So saying (2,4) means x = 2 and y = 4 pair together
Plug both of these values into the equation below
y = x-2
4 = 2-2
4 = 0
We get a false statement, so the original equation is false when (x,y) = (2,4)
---------------
Put another way, plugging x = 2 leads to...
y = x-2
y = 2-2
y = 0
But it should lead to y = 4 if (2,4) was a solution.
If your teacher said "(2,0) is a solution", then that would be a true statement.
