Use the following table to answer questions.
x y
1 7
3 ?
? 11
7 13
? ?
What are the values of x and y in the last row of the table?
What is the rule for this table?

  • Math -

    2 is added to the previous number.

  • Math -

    not nearly enough information, since only two ordered pairs are given.

    Is the relation linear? , then we could do it.

    slope = (13-7)/(7-1) = 1

    so y = x + 6

    so the table would be:

    1 7
    3 9
    5 11
    7 13
    ? ? , your choice

    however , as I implied there could be other rules

    e.g. y = (1/6)(x-1)^2 + 7 , also contains (1,7) and (7,13)
