Question

A line passes through the points (2,20) and (9,27) Write a linear function rule in terms of x and y for this line.

Answer 1

Answer: It would be x = y-18

Explanation:

When you line them up it would look like this

2,20

9,27

To get to 9 from 27 you would have to subtract 27 by 18 and you would get 9

To get to 2 from 20 you would have to subtract 20 by 18 and you would get 2.
