Question

Which ordered pair would form a proportional relationship with the point graphed below?

Answer 1

Answer:

$(x,y) = (-30,10)$

Step-by-step explanation:

Given

$(x,y) = (60,-20)$

Required:

Determine a pair with a proportional relationship

A proportional relationship is:

$k = \frac{y}{x}$

Where k is the constant of proportionality.

$(x,y) = (60,-20)$

So, we have:

$k = \frac{-20}{60}$

$k = -\frac{1}{3}$

This means that for a pair to have a proportional relation, k must be -1/3.

This is true for (c).

Where:

$(x,y) = (-30,10)$

So, we have:

$k = \frac{10}{-30}$

$k = -\frac{1}{3}$
