2.2 Parallel and Perpendicular Lines and Circles. Slopes and Parallel Lines If two nonvertical lines are parallel, then they have the same slopes. If two distinct nonvertical lines have the same slope, then they are parallel. Two distinct vertical lines, with undefined slopes, are parallel.

**2.2 Parallel and Perpendicular Lines and Circles**Slopes and Parallel Lines • If two nonvertical lines are parallel, then they have the same slopes. • If two distinct nonvertical lines have the same slope, then they are parallel. • Two distinct vertical lines, with undefined slopes, are parallel.**Example 1: Writing Equation of a Line Parallel to a Given**Line**Solution**X1=-2 Y1=-7**What is the slope of the line?**Given equation Slope of the line is –5.**Slopes and Perpendicular Lines**• If two nonvertical lines are perpendicular, then the product of their slopes is –1. • If the product of the slopes of two lines is –1, then lines are perpendicular. • A horizontal line having zero slope is perpendicular to a vertical line having undefined slope.**Solution Solve the given equation for y.**Slope is –3/2.**Definition of a Circle**A circle is the set of all points in a plane that are equidistant from a fixed point called the center. The fixed distance from the circle’s center to any point on the circle is called the radius.**The Standard Form of the Equation of a Circle**Center Any point on the circle**r=2**h=-4 k=-2
