Which ordered pair needs to be removed in order for the mapping to represent a function? (–3, –4)
(–2, –1)
(1, –3)
(3, 7)

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

step-by-step explanation:

i am pretty sure that the answer is 168

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
