A drone operator is programming a flight path. The drone starts at point (3, -2) and moves 5 units to the left and 4 units up. What are the new coordinates of the drone?
- A(-2, -6)
- B(8, -6)
- C(-2, 2)
- D(8, 2)
Show answer & explanationAnswer & explanation
Correct answer: C. (-2, 2)
Moving left means subtracting from the x-coordinate: 3 - 5 = -2. Moving up means adding to the y-coordinate: -2 + 4 = 2. The new coordinates are (-2, 2).
Why the other options are wrong
- A. This correctly subtracts from x but incorrectly subtracts from y.
- B. This incorrectly adds to x and subtracts from y.
- D. This incorrectly adds to x and adds to y.
Coordinate Plane Translation
Shifting a point on a coordinate plane by adding or subtracting values from its x and y coordinates.
- Left/Right affects x-coordinate (Left = subtract, Right = add).
- Up/Down affects y-coordinate (Up = add, Down = subtract).
- The shape and orientation of the object remain unchanged.
Memory trick: Coordinates are Key to Clear Locations.
