Question

If -8 = y and -2 = x, how do you find x when y= 32?

Answer 1

You can write a relationship between `x` and `y` in the form:
`y=kx`
Where `k` is a constant of proportionality that you can find by substituting:
`x=-2` and `y=-8`
giving: `-8=-2k`
and `k=4`
Now that you know `k` use the same relationship, that now reads `y=4x`, to find `x` when `y=32`...try it!
