hey i want to know the best book and the way to prepare coordinate geometry

I am facing a bigtrouble in it.

dear student 
you need to clear the besics of algebra and trigo . if u want coordinate geo to understand properly . 
and the lower class geometry also like plotting the points . 
you can take the book of cengage publication / m l khanna , there its written in precise manner . 

check with your comfortability between any one of them .

kindly approve
