Question

What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?

Answer 1

Solution :-

Distance = √(x2 - x1)² + √(y2 - y1)²

Distance = √(7 - (-8))² + √(8 - 0)²

Distance = √(7 + 8)² + √(8)²

Distance = √(15)² + √(8)²

Distance = √(225 + 64)

Distance = √(289)

Distance = 17 unit

Answer 2

17 units

Explanation:

Going from one point to the other, the change in x is 15 and that in y is 8. Therefore, applying the Pythagorean Theorem,

distance = √(225 + 64) = √289 = 17

The distance between the two points is 17 units.
