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.

X1=-2

Y1=-7

what is the slope of the line
What is the slope of the line?

Given equation

Slope of the line is –5.

slopes and perpendicular lines
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.
definition of a circle
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.
