Question

Three points of a function are graphed.

A coordinate plane with 3 points plotted at (10, 18), (14, 24), and (18, 30).
Which statement describes the function through the points?

The function is a direct variation function with a constant of variation of 1.5.
The function is a direct variation function with a constant of variation of 1.8.
The function is linear but is not a direct variation function.
The function is not a linear function.

Answer 1

Answer:

The function is linear but is not a direct variation function.

Step-by-step explanation:

Let say y = mx + c

(10, 18), (14, 24), and (18, 30).

18 = 10m + c

24 = 14m + c

30 = 18m + c

4m = 6

m = 1.5

c =3

y = 1.5x + 3

Hence it does not pass through origin

The function is linear but is not a direct variation function.
