# How do you write the point slope form of the equation given (1,9) and (-2,-2)?

##### 1 Answer

See the entire solution process below:

#### Explanation:

First, we must determine the slope. The slope can be found by using the formula:

Where

Substituting the values from the points in the problem gives:

The point-slope formula states:

Where

We can now substitute the slope we calculated and the values from the first point giving:

We can also substitute the slope we calculated and the values from the second point giving:
