Linear Function:

x y
-1 10
0 14
1 18
2 22

The rate of change of the linear function is

The y-intercept of the linear function is

Arithmetic Sequence (Explicit formula):

an = 10+ 4(n−1)


The rate of change (common difference) of the arithmetic sequence is

The first value of the arithmetic sequence is

The rate of change of this linear function is

Answer 1

- Rate of change of the linear function: 4
- Y‑intercept of the linear function: 14

- Rate of change (common difference) of the arithmetic sequence: 4
- First value of the arithmetic sequence: 10

The rate of change of this linear function is equal to the rate of change of this arithmetic sequence.

Yes — arithmetic sequences can be represented as linear functions (e.g. an = 10 + 4(n−1) is linear in n; the given linear function is y = 4x + 14).
