Question

Write in standard form the equation of the line that has a slope of 2 and that passes through ( 3, -1) explain please!

Answer 1

Standard form.


`y=mx+n`

Where m is the slope and n is the point where x=0. Then, you have,

`y=2x+n`


To obtain n use the point they give you,


`-1=2(3)+n`

So n=-7 and then


`y=2x-7`
