Question

What is the equation of the trend line?

Enter your answers in the boxes.

N =
M +

Answer 1

N = -2 M + 110

Answer 2

`N=-2M+110`

Explanation:

we know that

The equation of the line in slope-intercept form is equal to

`N=mM+b`

where

m is the slope of the line

b is the N-intercept

In this problem we have

`b=110`

Find the slope

Let

`A(20,70),B(0.110)`

`m=(110-70)/(0-20)=-2`

substitute the values

`N=-2M+110`
