Question

Given L(-4,3) and M(-7,-2), what is the length of LM?

Answer 1

A.√34

Explanation:

The distance between two points is given by the square root of the addition of the square of the differences of the points along the x and y axis.

Where the distance is d, the points are (x₁,y₁) and (x₂,y₂)

d = √(x₂ - x₁)² + (y₂ - y₁)²

d = √(-7 - -4)² + (-2 - 3)²

d = √(-3)² + (-5)²

d = √34

Answer 2

-7 --4 = -7 +4 = -3, -3^2 = 9

-2-3 =-5, -5^2 =25

9+25 = 34

answer is A sqrt(34)
