Question

Point slope equations

Answer 1

The point slope equation is: y - y1 = m (x - x1)

m = slope

Explanation:

To use this equation, you need to know:

- one point on the line

- the slope of the line

First:

(x1,y1) = a known point on the line

m = the slope

(x,y) = any other point on the line

Now:

we plug the numbers into the equation to get y - y1 = m (x - x1)

Then:

you solve the equation
