Variables a and b represent positive numbers. Luciana plots points P with coordinates (-a, -b) in the coordinate plane. She reflects that point across the x-axis. In which quadrant is the reflection of point P in the coordinate plane?

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Carrie wants to plot point K at (-3, 9) and point L at (6, -1) in the coordinate plane. How should Carrie plot these points in the coordinate plane?

To plot point K, Carrie should start at the origin and move 3 units ​ (a)   and then 9 units ​ (b)   . To plot point L, Carrie should start at the origin and move 6 units ​ (c)   and then 1 unit ​ (d)   .
