Question

What are two points that represent Justine's function for the yards left to hike in terms of the hours she's spent hiking?

Answer 1

Select any two pairs of values from the given table. But, for simplicity, it’s a good idea to select coordinates with integer values. So, two points that represent Justine’s function for the yards left to hike in terms of the hours she’s spent hiking are (1, 270) and (2, 150).

Answer 2

(0,320) and (4,0)

Explanation:

The question has missing details. So, I've added the complete question as an attachment.

From the question, we understand that:

Justine started when Michael was 320 yards from the top.

This coordinate can be represented as (0,320)

0 represents the time Justine started and 320 represents the number of yards left.

Every minute, Justine covers 80 yards.

This implies that:

At 1 minute, Justine will have: (320 - 80) yards left

At 2 minutes, Justine will have: (320 - 80 - 80) yards left

At 3 minutes, Justine will have: (320 - 80 - 80 - 80) yards left

At n minutes, Justine will have (320 - 80n) yards left

So, possible coordinates are:

`(x_1,y_1) = (0,320)`

`(x_2,y_2) = (1,320-80*1) = (1,240)`

`(x_3,y_3) = (2,320-80*2) = (2,160)`

`(x_3,y_3) = (3,320-80*3) = (3,80)`

`(x_4,y_4) = (4,320-80*4) = (4,0)`
