Question

What is the length of AB? A(2,-6). BIZ, 1)

Answer 1

Answer:

The length of AB is $\sqrt{74}\ units$

Step-by-step explanation:

we know that

The formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(2,-6)\\B(7,1)$  

substitute

$d=\sqrt{(1+6)^{2}+(7-2)^{2}}$

$d=\sqrt{(7)^{2}+(5)^{2}}$

$d=\sqrt{49+25}$

$AB=\sqrt{74}\ units$
