Question

How do you write an equation of the line in point slope form with slope =3, (4,-8)?

Answer 1

`y=m*x+b`
Where `m=`slope and `b=y`-intercept

Explanation:

If we use the known data (slope and one known `x,y`:
`-8=3*4+b->b=-20`

So the equation: `y=3x-20`
graph{3x-20 [-39.88, 52.64, -24.55, 21.7]}
