In order to solve this exercise, you need to remember the following definitions:
1. The slopes of Paralell lines are equal.
2. The slopes of Perpendicular lines are opposite reciprocals.
The equation of a line in Slope-Intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.
In this case you have the following equation of a line written in Slope-Intercept form:

So you can identify that the slope of this line is:

Therefore, you can determine that the answers are:
-The Slope of a parallel line is:

- The Slope of a perpendicular line is:
