# How do you write an equation in point slope form given (-0.5, 0.9), (-3.3, -0.5)?

##### 1 Answer

#### Explanation:

For the line segment from

the change in

and

the change in

Slope is defined as

So, in this case,

For a line with a slope of

the point-slope form of the equation is

We could use either of the given points as

As an example if we choose

then the equation of our line would be

or

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Alternately, if we had chosen

the resulting equation would be

With a bit of manipulation these equations can be shown to be identical.
