Question

A campsite charges $12 per day for the site rental and $8 for parking . The total campsite charge C (in dollars) is given by C=12d+8 where d is the number of days that the site is rented . Graph the equation

Answer 1

We are given equation of total campsite charge

$C=12d+8$

where

C is total campsite charge C (in dollars)

d is the number of days that the site is rented

so, here we will have

C is y-axis or dependent variable

d is x-axis or independent variable

we can find any two points and then we locate it

after that we can join them to get our graph

At d=0:

$C=12\times 0+8$

$C=8$

so, our point is (0,8)

At C=0:

$0=12d+8$

$-8=12d$

$d=\frac{-2}{3}$

so, our point is $(\frac{-2}{3},0)$

now, we can locate these points and then join it
