Question

What is the length of line segment CD with endpoints (-3, 2) and (2, 2) as shown on the coordinate plane?

Answer 1

Check the picture below.

Answer 2

Answer: CD = 5

Explanation:

Given;

x₁ = -3 y₁ =2 x₂ = 2 y₂ =2

CD = √(x₂ -x₁)² + (x₂ - x₁)²

= √(2+3)² +(2-2)²

= √(5)²

=√(25)

=5

Therefore CD = 5
