The distance between two points is the number of units between them.
<u>Halfway points (a) and (b)</u>
To locate a point halfway points (a) and (b), we use the following steps
- Calculate the absolute difference between both points
- Divide the absolute difference by 2
- Add the quotient to the smaller point.
Assume the smaller value is (a), the point (P) halfway points (a) and (b) would be
Take for instance, a = 5, and b = 10.
The halfway point would be:
The halfway point between 5 and 10 is 7.5
The formula works for negative values, and absolute values are used to return the actual difference between both points
<u>Real world circumstance</u>
The formula can be used to calculate the halfway distance between a school gate and the school library (as an instance)
<u>Fractional distance</u>
To determine the fractional distance, we simply replace the 1/2 in the original formula with the appropriate fraction.
Take for instance, three-fourths from (a) to (b) would be:

Answer:
8√5 units.
Step-by-step explanation:
See the diagram in the coordinate plane attached.
A rhombus has four equal sides and to find the perimeter of the rhombus we have to measure any of the sides of the figure of the rhombus.
The coordinates of the topmost point are (-1,-1) and that of the rightmost point are (3,-3).
Therefore, side length of the rhombus will be
units.
So, the perimeter of the rhombus will be (4 × 2√5) units = 8√5 units. (Answer)
The distance between two points and
on a coordinate plane is given by
