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