Question
What is the distance between the following ordered pairs (- 2, 12) and (7, 12)?
3 units
5 units
9 units
1 unit
Hint:
Distance is a numerical measurement of how far apart objects or points are. Absolute value is the magnitude of a real number without regard to its sign. Also called modulus
The correct answer is: 9 units
Step 1: If the y - coordinates are the same, we use the x - coordinates to find the distance. Step 2: Add absolute values of the coordinates to find the distance between the points since they lie in different quadrants. Step 3: ∣ - 2∣ + ∣ 7 ∣ = 2 + 7 = 9
