Question

Kyle notices that the number of likes he receives each day on his social media page is a function. He decides to create a graph representing the feedback over one month. So far he has collected the following data: (0, 0), (1, 12), and (2, 24), where x represents days and y represents likes.

How many likes would Kyle receive on the 30th day?
A) 30
B) 96
C) 144
D) 360

Answer 1

D) 360

Explanation:

The data Kyle collected is (0, 0), (1, 12), and (2, 24), where x represents days and y represents likes.

We can write a linear function to model this situation.

This will be of the form

`y = mx`

because it passes through the origin , where m is the slope.

The slope is

`m = (12 - 0)/(1 - 0) = 12`

Hence the equation is

`y = 12x`

To find the number of likes on the 30th day, we put x=30 into the equation to get:

`y = 12 * 30 = 360`

The correct choice is D
