I just took the test Hope this helped :D

Answer 2

Answer: The value of m = 10.

Explanation:

Given points, (1,5), (9,85), (2,10), (6,38), (4,3), (12,107), (7,64), (12,86), (7,47), (9,64), (4,27)

Each point is represented in the form (x,y).

The line is in the form
`y=mx+b`, where m is the rate of change of y with respect to x.

`m=(y_2-y_1)/(x_2-x_1)`

Take
`x_1=1\ \ , y_1=5;\ \ x_2=9,\ \ y_2=85`

Then,

`m=(85-5)/(9-1)\\\\=(80)/(8)=10`

Hence, the value of m = 10.
