Aline has a slope of -4/5. which ordered pairs could be points on a line that is perpendicular to this line? check all that apply. (–2, 0) and (2, 5) (–4, 5) and (4, –5) (–3, 4) and (2, 0) (1, –1) and (6, –5) (2, –1) and (10, 9)

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:
