The following dot plot represents student scores on the Unit 1 math test. Scores are in whole number increments.

For this data set, the value of the range is about the value of the interquartile range.

On average, the data points lie between points from the mean.

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

graph of this function as shown below:

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
