Question

Point A is located at (1, 5), and point A′ is located at (-2, 1). What is the distance from B to B′ ?

Answer 1

Answer:

The distance between B to B' is 5

Step-by-step explanation:

Using the distance lie formula:

Let's say (x2, y2) is (-2,1) and (x1, y1) is (1,5)

$\sqrt{(x2-x1)^{2} +(y2-y1)^{2} } \\\sqrt{(-2-1)^{2} +(1-5)^{2} } \\\sqrt{(-3)^{2} +(-4)^{2} } \\\sqrt{9+16}\\\sqrt{25} \\= 5$

The distance between the original and new coordinates would be the same, therefore the two will remain a distance of 5.
