Question

pythagorean distance
what is the vertical distance b?
points: (-2, 11) (-5, 7)
a = δx = 3
b = ?
pythagorean formula c² = a² + b²

Explanation:

Step1: Recall vertical distance formula

Vertical distance between two points \((x_1,y_1)\) and \((x_2,y_2)\) is \(|y_1 - y_2|\).

Step2: Substitute the y - coordinates

Given points \((-2,11)\) and \((-5,7)\), \(y_1 = 11\), \(y_2=7\).
So \(b=\vert11 - 7\vert=\vert4\vert = 4\).

Answer:
