Which relation is a direct variation that contains the ordered pair (2,7)?

D.

Step-by-step explanation:

We are asked to find the equation, which represents the direct variation that contains the ordered pair (2,7).

When two quantities are proportional to each other, they are in form , where, k represents constant of variation.

Upon substituting and in above equation, we will get:

Let us solve for k by dividing both sides by 2:

Therefore, our required equation would be and option D is the correct choice.

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
