The number of right handed students in a mathematics class

There is no photo or anything that could help me solve this.

Step-by-step explanation:

If I am wrong and there is no evidence for this, the number of right handed students in a mathematic class can be absolutely random. You never know who uses the right hand or left hand unless you pay attention, it could even be 50/50. The chances are not determined.

Hahaha, hope this helped!

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
