It is not displaying both plots

x=[2012 2013 2014 2015 2016 2017]

y=[10 10.9 11.7 12.6 13.8 14.9]

plot(x,y,'dk')

xlabel('Año')

ylabel('Eje y')

title('Población')

hold on

sxy=sum(x.*y)

sx=sum(x)

sy=sum(y)

sx2=sum(x.^2)

csx=sum(sx)^2

n=length(x)

m=((n*sxy)-(sx*sy))/(n*sx2-(csx))

b=(sy-m*sx)/n

f=m*x+b

a=["y=" m "x" "+" b]

disp(a)

plot(f)

Answer 1

Plot ‘f’ as a funciton of ‘x’ —

plot(x,f)

.

This obviously worked because you quoted it in How to find Coefficient R.
