Presentation transcript:

I can determine when lines are parallel and write equations of parallel lines.

 Lines in the same plane that never intersect.  Nonvertical lines are parallel if they have the same slope and different y-intercepts.  Vertical lines are parallel if they have different x-intercepts.  Ex:  Same slope, different y-intercept

 A line that passes through (-3, -1) is parallel to the graph of y = 2x + 3. Write the equation of the line in slope-intercept form.  y = 2x + 5

I can determine when a line is perpendicular and write equations of perpendicular lines.
