Question

Which of the following ordered pairs could be placed in the table below and still have the relation qualify as a linear function?

−5 7
−3 15
−1 23
? ?

Answers:
(0, 31)
(−7, 30)
(1, 31)
(0, −1)

Answer 1

in a linear function, both variables change at the same constant rate

for example, if you look at the above example, notice how the left column is increasing by 2 each time, and the right column is increasing by 8

try to continue this pattern from (-1,23) to find the next point

Answer 2

Thank you!
