The standard form of the equation of a line is given in the form:

where A, B, and C are constant integers.
We can write the equation in the point-slope form first, before getting the standard form of the equation:

where m is the slope, calculated using the formula:

Using the points, the slope will be:

The answer is undefined. Therefore, the line is a vertical line.
Given it is a vertical line, the equation will be in the form:

At the point (3, 6), we have that:

Therefore, the equation of the line will be:
