Question

A grid shows the positions of a subway stop and your house. The subway stop is located at (7,-6) and your house is located at (-9,5). What is the distance, to the nearest unit, between your house and the subway stop?

Answer 1

Answer:

The distance is $19\ units$

Step-by-step explanation:

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

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

In this problem

Let

$Subway\ Stop(7,-6)\\House(-9,5)$  

substitute the values

$d=\sqrt{(5+6)^{2}+(-9-7)^{2}}$

$d=\sqrt{(11)^{2}+(-16)^{2}}$

$d=\sqrt{377}\ units$

$d=19\ units$
