Question 9 Multiple Choice Worth 1 points) (02.03)
Below are the steps to solve an equation:
Step 1: IX - 21 + 3 = 7
Step 2: - 2 = 7 - 3
Step 3: IX - 21 = 4
Which of the following is a correct next step to solve the equation?
Ox+ 2 = -4
O-x - 2 = 4
Ox+ 2 = 4
Ox-2=-4

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
