# How do you find a standard form equation for the line with P= (-5,-5) and Q= (-3,-2)?

##### 1 Answer

(see below for method)

#### Explanation:

**Step 1: Develop a slope-point form for the line**

The slope of a line between two points is defined as:

This relationship must hold for any arbitrary point

so

Therefore

or

**Step 2: Convert the slope-point form into standard form**

Note that the standard form for a linear equation is

If

then

or
