Question

The coordinates of Jack’s house are ( – 8, 5 ) and the coordinates of Jill’s house are (8, 5). Find the distance between Jack’s house and Jill’s house.

  1. 3 units    
  2. 10 units    
  3. 16 units    
  4. 13 units    

hintHint:

Distance is a numerical measurement of how far apart objects or points are.
Absolute the magnitude of a real number without regard to its sign. Also called modulus

The correct answer is: 16 units


    Step 1: If the y-coordinates are the same, we use the x-coordinates to find the distance.
    Step 2: Add the absolute values of the coordinates to find the distance between the points since they lie in different quadrants.
    Step 3: ∣- 8∣ + ∣ 8 ∣ = 8 + 8 = 16
