So, last friday we started a new unit called "DISTANCE BETWEEN POINTS."
DISTANCE FORMULA:
Find the distance between a(3,6) and B(7,9).
ex.
The distance between two points can be expressed in terms of their coordinates by using the Pythagorean theorem.
In a right triangle, the square of the length of the hypotenuse (longest side) is equal to the sum of the squares of the lengths of the other two sides.
