Answer 1

Answer:

a) Linear b) Non-linear

Step-by-step explanation:

a) Watch the increments of x and y

As the x values increase by 1, the y values decrease by 3 constantly. There is no change between these increments so the relationship is linear.

I'm not sure what the First Difference means but the y value decreased by 4 and the x value increased by 1.

From 10 to 7 (y) and from 1 to 2 (x)

b) Watch the increments of x and y

As the x values increase by 1, the y-values do not continuously increase or decrease by the same increment. First, the y-value goes from 3 to 6 (an increase of 3), then 6 to 10 (an increase of 4), then 10 to 15 (an increase of 5)

Since the y-value increases by different amounts on different x-values, the relationship is not linear.

The First Difference would probably be x goes from 1 to 2 and y goes from 3 to 6

I hope this helped! :)
