Question

How do you solve `y - 3= \frac{1}{4} ( x - 3)`?

Answer 1

Assuming that we are trying to convert the given equation into a simple functional expression for `y`:
`color(white)("XXX")y=1/4(x+9)`

Explanation:

Given
`color(white)("XXX")y-3=1/4(x-3)`

then
`color(white)("XXX")y-12/4=1/4x-3/4`

`color(white)("XXX")y=1/4x-3/4+12/4`

`color(white)("XXX")y=1/4x+9/4`
or
`color(white)("XXX")y=1/4(x+9)`
