Sagot :
Both the x-values and the y-values have to be the same.
This is true for all of them except (12, 14) because 12 does not equal 14.

y=x
If we plug in the values of points (x,y) into that equation then we will find out if they are in that line.
So (0,0) is in the form of (x,y). So we plug that into x=y
And 0=x, and 0=y. So 0=0
Since that equals to each other, that is the wrong answer.
Do the same for the other points:
(6,6) same in the form os (x,y)
So plug it in to x=y, and 6=6
So this point is also in the graph og the equation y=x.
And we notice that y=x will only be satisfied when both x and y in (x,y) are the same. And we notice that answer choice D is the only one that doesn't fit it.
So D is your answer :)
