Alumber yard sells pre-cut 6-, 8-, 10-, and 12-foot beams for $1.20 per foot. model the situation with a linear function.

y = 1.20x

Step-by-step explanation

Let's call x the length of the beams in feet

Llamemps f (x) at the price of beams.

The function represented by this model is the line y = 1.20x

Where 1.20 is constant price per foot.

If the price per foot is $ 1.20, then, the price of each beam according to its size is:

6 * 1.20 = $ 7.2

8 * 1.20 = $ 9.6

10 * 1.20 = $ 12

12 * 1.20 = $ 14.4

Then we have the following points, which will constitute the domain and rank for the function:

(6, 7.2)

(8, 9.6)

(10, 12)

(12, 14.4)
