1
**Parallel and Perpendicular Lines**

Write the equation of a line that passes through a given point, parallel to a given line. Write the equation of a line that passes through a given point, perpendicular to a given line.

2
Parallel lines Lines in the same plane that do not intersect are called parallel lines. Parallel lines have the same slope.

3
Perpendicular Lines Lines that intersect at right angles are called perpendicular lines. The slopes of these lines are opposite reciprocals. Opposite reciprocals???? 3…..

4
**neither parallel perpendicular**

From the given equations, determine if the corresponding lines are parallel, perpendicular, or neither. y = 2x + 2 y = 4x - 2 neither 2x + 6y = 1 4x + 12y =3 parallel perpendicular

5
Write the slope intercept form of an equation for the line that passes through (12,3), and is parallel to the graph of

6
Write the slope intercept form of an equation for the line that passes through (1, -3), and is perpendicular to the graph of

7
Write the slope intercept form of an equation for the line that passes through (-6, 5), and is perpendicular to the graph of x - y= 5
