### Example Question #2 : Standard Form

Refer to the above red line. What is its equation in standard form?

**Possible Answers:**

**Correct answer:**

First, we need to find the slope of the above line.

Given two points, , the slope can be calculated using the following formula:

Set :

Second, we note that the -intercept is the point .

Therefore, in the slope-intercept form of a line, we can set and :

Since we are looking for standard form - that is, - we do the following:
