Question

How do you write the equation in point slope form given m=-2; (0,1)?

Answer 1

`(y-1) =-2x -> y =-2x+1`

Explanation:

The equation of a straight line of slope (`m`) pasing through the point `(x_1, y_1)` is given by:

`(y-y_1) = m(x-x_1)`

In this example `m=-2, x_1=0, y_1 =1`

Hence the equation of the line is:

`(y-1) =-2(x-0) -> (y-1) =-2x`

`y =-2x+1`
