1. Objective - To write equations of parallel and perpendicular lines. Graph the following on the coordinate plane. x y Parallel lines have the same slope.

2. Find the equation of a line in standard form that is parallel to 3x - 5y = 10 and contains (-2,6). 3x - 5y = 10 -3x -5y = -3x + 10 -5 (-2,6) or

3. Graph the following on the coordinate plane. x y Lines appear perpendicular Perpendicular lines have slopes that are opposite reciprocals

4. Find the following: Number OppositeReciprocal Opposite Reciprocal 3 0.2 -8

5. 4 Find the equation of a line in standard form that is perpendicular to 4y - x = 6 and contains (2,5). 4y - x = 6 +x 4y = x + 6 (2,5)

6. Determine whether the slopes are perpendicular. 1) 2) 3) Yes, perpendicular. No, not perpendicular. Yes, perpendicular.

7. Find the equation of a line in standard form that is perpendicular to 3x + 5y = 7 and contains (-4,-8). 3x + 5y = 7 -3x 5y = -3x + 7 5 (-4,-8) or
