Answer 1

if im correct it should be N=-2 m+110

Answer 2

`N=-2M+110`

Explanation:

Find the slope m

we know that

The formula to calculate the slope between two points is equal to

`m=(N2-N1)/(M2-M1)`

we have

`A(0,110), B(20,70)`

Substitute the values

we have

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

`m=(-40)/(20)`

`m=-2`

Find the equation of the line in slope-intercept form

`N=mM+b`

where

m is the slope of the line

b is the N intercept

In this problem we have

`m=-2`

`b=110`

Substitute

`N=-2M+110`
