[Video] Q16: Several values of x and their corresponding values of y are shown in the table. a linear equation that represents the relationship shown in the table x=k, where k is a constant. what is the value of k?

Explanation for Question 16 From the Math (No Calc) Section on the 2020 October Sat

So question 16 gives us a table of a function. 2 And then it goes ahead and tells us that this, 3 um, equation is X equals K, 4 where K is a constant. And if K is constant, 5 then that means that Cain never changes. And if K never changes, 6 then that means that X never changes. And we can ask ourselves, 7 does that make sense? Is X ever changing in this function? 8 If we look at our X values, we can see the X is always 9 two. If we were to graph this, 10 it would look like a vertical line going straight through to because X is 11 to no matter what your Y value is. 12 And so remember, K is what X is equal to an X is equal 13 to two throughout this entire function. So our answer is going to be two.
