Question

What is the equation of the line with slope `m= 8/25` that passes through `(42/5 21/10)`?

Answer 1

I found: `y=8/25x-147/250`

Explanation:

You could use the general expression for a line thrugh `(x_0,y_0`) and slope `m` given as:
`y-y_0=m(x-x_0)`
giving:
`y-21/10=8/25(x-42/5)`
rearranging:
`y=8/25x-336/125+21/10`
`y=8/25x-[(3360-2625)/1250]`
`y=8/25x-cancel(735)^147/cancel(1250)^250`
`y=8/25x-147/250`
