The distance between (-18, 9) and (22, 0) = 41 units.
What is the distance formula for two given points?
The distance formula for two given points (x₁,y₁) and (x₂,y₂) is given by,
D = √((x₂-x₁)² + (y₂-y₁)²)
How do we calculate the distance between (-18,9) and (22,0)?
We will use the formula as discussed above,
D = √((22-(-18))² + (0 - 9)²) = √(40² + (-9)²) = √(1600 + 81) = √1681 = √41²
∴ D = 41
∴ The distance between (-18, 9) and (22, 0) = 41 units.
