Question

The ordered pair (8,5) represents a point on the graph of a proportional relationship. Which ordered pair also represents a point on the same graph? A. (5/8, 1) B. (1, 5/8) C. (5,8) D. (1, 8/5)

Answer 1

Given the ordered pair:

(8, 5)

Let's find the ordered pair that represents a point on the same graph assuming this is a graph of a proportional relationship.

Here, we have:

(x, y) ==> (8, 5)

Since this is a graph of a proportional relationship, let's find the constant of proportionality.

We have:

$K=\frac{y}{x}=\frac{5}{8}$

This means when x is 1, y is 5/8.

Thus, the ordered pair that also represents a point on the same graph is:

$(1,\frac{5}{8})$

ANSWER:

$\text{ B. (1, }\frac{5}{8})$
