What is the equation of the trend line?
Enter your answers in the boxes.
N =
M +

Answer:
[tex]N=-2M+110[/tex]
Step-by-step explanation:
we know that
The equation of the line in slope-intercept form is equal to
[tex]N=mM+b[/tex]
where
m is the slope of the line
b is the N-intercept
In this problem we have
[tex]b=110[/tex]
Find the slope
Let
[tex]A(20,70),B(0.110)[/tex]
[tex]m=(110-70)/(0-20)=-2[/tex]
substitute the values
[tex]N=-2M+110[/tex]
