The slope of the line below is -2. Write the point-slope equation of the line
using the coordinates of the labeled point.
(4.-6)

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:

m: It is the slope of the line

: It is a point through which the line passes.

We have to:

Thus, the equation is of the form:

We substitute the point

Finally, the equation is:
