What is the slope of the line containing the points (17,92) and
(21, 44)?

-12

Step-by-step explanation:

Formula:

Identify the values:

Plugin the values; solve:

Therefore, the slope of the line containing the points (17,92) and

(21, 44) is -12.

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:

y > 1/3x

y < = -x + 4
