Question

If y

=
Y kx
=
48 when x = 80, what is the value
of k?
Give any decimal answers to 1 d.p.

Answer 1

0.6

Explanation:

You are told the equation is
`y = kx`

You know the value of
`y` is 48 when
`x` is 80.

Therefore, we can substitute these answers into the equation:

`48 = 80k`

This means that to solve for
`k`, we must divide the 80 over:

`k = (48)/(80) = (6)/(10) = (3)/(5) = 0.6`

Therefore,
`k = 0.6`.
