Question "how does a ratio can be negative I have studied in calculus that a line is divided internally in the ratio 3:-2 I think the ratio is always positive how line can be divided in negative ratio explain?"

Answer A negative ratio is a negative correlation, which means as x increases, y would decrease. So let's use a relationship between education and crime rates. As the amount of educators increase, the crime rates go down because the children now know what's right and wrong.

If the ratio is 3:-2, then it's the same thing as 3/-2, which is basically -3/2 or -1.5.

Anything from elementary to high school is fair game. I'm also experienced in standardized testing, such as SAT subject test math level 2, SAT math portion, and AP Calculus exam.
The only problems I will have difficulty in are those that have no relevance to Algebra itself such as Geometry and number theory.

Experience

I have taken: Algebra, Geometry, Algebra 2, Math Analysis (Pre-Calculus), and AP Calculus AB. I have received all A's for each year other than one semester in Math Analysis when I was transferring schools.
I tutor after school at the library, usually focusing on Algebra for the most part.

Organizations I am: Officer of Asian club; President of SAFE club; KDE-RC1 Judge

Education/Credentials 770 on SAT math portion, 5 on AP Calculus Exam, and 750 on SAT subject test math level 2
