Question

Find AB if A(-9,2) and B(5,-4)

Answer 1

The given points, A and B form a line, AB

We would determine AB by applying the formula for determining the distance between 2 points. It is expressed as

`\begin{gathered} \text{Distance = }√((x2-x1)^2+(y2-y1)^2) \\ \text{From the information given,} \\ x1\text{ = - 9, x2 = 5} \\ y1\text{ = 2, y2 = - 4} \\ \text{Distance = }√((5--9)^2+(-4-2)^2) \\ \text{Distance = }√(14^2+(-6)^2) \\ \text{Distance = }√(196+36) \\ \text{Distance = }√(232) \\ \text{Distance = 15.23} \end{gathered}`

AB = 15.23
