Question

The ordered pairs below represent a relation between x and y.
(-3,1), (-2,3), (-1,5), (0,7), (1,9), (2,11)
Could this set of ordered pairs have been generated by a linear function?
Yes, because the distance between consecutive x-values is constant
No, because the distance between consecutive y-values is different than the distance between consecutive x-values
Yes, because the relative difference between y-values and x-values is the same no matter which pairs of (x, y) values you use to calculate it
No, because the y-values decrease and then increas

Answer 1

Yes, because the relative difference between y-values and x-values is the same no matter which pairs of (x,y) values you use to calculate it.

Answer 2

Shouldn't you try to help them figure out the answer, instead of just giving it to them?

Answer 3

Yes, because the relative difference between y-values and x-values is the same no matter which pairs of (x, y) values you use to calculate it

Answer 4

Hope I helped:)
