Question

The values of x and y are directly and one pair of values are given.

Answer 1

Answer:

The relation is $y = -1.5x$

Step-by-step explanation:

x and y are directly proportional:

This means that the equation is given by:

$y = ax$

In which a is the multiplier that relates these two variables.

x= -4, y =6

We use this to find a. So

$y = ax$

$6 = -4a$

$a = -frac{6}{4}$

$a = -1.5$

So

The relation is $y = -1.5x$
