Which type of data would be BEST displayed in a

dot plot?

the number of dentists volunteering their

time in each of the last 15 school dental

clinics (range: 3-28)

the number of students seen in a school

clinic that did not have any cavities

the number of toothbrushes distributed

each month for the last 24 months

(range: 725-2450)

the number of miles the dental clinic bus

travelled each month for the last 60

months (range: 700-1875)

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
