Question

Point A is located at (−5, 2) on a coordinate grid. Point A is translated 8 units to the right and 3 units up to create point A'. Which measurement is closest to the distance between point A and point A' in units?

Answer 1

Answer:

i think 9 units

Step-by-step explanation:

Answer 2

Answer:

$\sqrt{73}$ units

Step-by-step explanation:

1. Think of it as a triangle. (-5, 2) is the starting point (one vertex). Use pythagorean theorem to solve.

Leg 1: 8 units (to right)

Leg 2: 3 units (upwards)

Leg 3: $8^{2} +3^{2} = x^{2}$

Solve for x because hypotenuse gives the distance between the two points.
