Name _____________________________________________________ Date __________________ Score _________

1. Which line is parallel to, $y = 3x + 5$? 20 points $y = \frac{1}{3}x + 2$ $y = -\frac{1}{3}x + 2$ $y = 3x + 2$ $y = -3x - 5$
2. Which line is perpendicular to, $y = 3x + 5$? 20 points $y = \frac{1}{3}x + 2$ $y = -\frac{1}{3}x + 2$ $y = 3x + 2$ $y = -3x - 5$
3. Which line is perpendicular to, $y = -5$? 20 points $y = -2$ $y = \frac{1}{2}x + 5$ $x = 2y$ $x = 2$
4. Which equation is parallel to $y = 3x -7$ and passes through the point $(6, -2)$? 20 points $y = 3x - 4$ $y = 3x + 4$ $y = \frac{1}{3}x + 4$ $y = \frac{1}{3}x - 4$
5. Which equation is parallel to the y-axis? 20 points $y = 6x + 4$ $y = 8x - 2$ $y = 8$ $x = 12$
6. Which equation is parallel to the x-axis? 20 points $y = 6x + 4$ $y = 8x - 2$ $y = 8$ $x = 12$
