Answer:
Which y coordinate? Please specify...
Step-by-step explanation:
Distance between two points formula:
√(x₂ - x₁)² + (y₂ - y₁)²
Since the y-coordinates are the same, they eliminate each other in the formula and therefore they will be 0.
New formula (for points that have the same y-coordinates):
√(x₂ - x₁)²
Eliminate √ and ² since they cancel each other out.
Basically:
x₂ - x₁
Example:
(2,4) and (6,4)
6 - 2 = 4
The distance is 4.
