Let

P-------> the number of pages Margaret has left to read

d-------> the number of days Margaret has been reading

we know that

[tex]P=276-35d[/tex]

This is a linear equation

where

[tex]-35[/tex] ------> is the slope of the equation

represent [tex]35\frac{pages\ read}{day}[/tex]

[tex]276[/tex] ------> the total number of pages in the book

[tex]35d[/tex] ------> the number of pages she has read during d days
