Question

How do you find the direct variation equation which passes through (0, 0) and (4, 1)?

Answer 1

`y=1/4x`

Explanation:

`"the initial statement is "ypropx`

`"to convert to an equation multiply by k the constant"`
`"of variation"`

`rArry=kx`

`"to find k use the given condition"`

`(4,1)rArrx=4,y=1`

`y=kxrArrk=y/x=1/4`

`"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=1/4x)color(white)(2/2)|)))`
