Question

The set of ordered pairs below represents a linear function.

{( -2, -3), (0, -2), (2, -1), (x,y)}
What is one other pair of coordinates that could be the missing ordered pair (x,y), in this set?

Answer 1

(4,0)

Explanation:

you add 2 to the x cordinate and add 1 to the y cordinate.

Answer 2

(4,0)

Explanation:

It is a linear function so you find the slope by doing y2-y1/x2-x1 and you find the slope to be 1/2. You can then setup an equation using it and graph it to find the next value.
