Question

For the direct variation function y=kx(where>0) as the value of x increases the value of y ? A Increases B Decreases C Decreases then increases D is equal to k

Answer 1

Increases

Explanation:

Given

`y = kx`

`k > 0`

Required

What happens to y when x increases

Since k > 0.

It' safe to assume that:

`k = 2`

Solving further, we assume two increasing values for x

FIrst.

`x = 4`

`y = kx`

`y = 2 * 4`

`y= 8`

Next;

`x = 6`

`y = kx`

`y = 2 * 6`

`y = 12`

Notice that: as x increases from 4 to 6, y increases from 8 to 12

Hence:

Option A answers the question
