Question

A grid shows the positions of a subway stop and your house. The subway stop is located at (-1, 9) and your house is located at (2, -4). What is the distance, to the nearest unit, between your house and the subway stop? A.) 5 B.)6 C.)12 D.)13

Answer 1

The distance between the house and the subway is given by:
d=√[(x-x1)²+(y-y1)²]
Thus given the coordinates:
(-1,9) and (2,-4)
thus
d=√[(2-(-1))²+(-4-9)²]
d=√[(3)²+(-13)²]
d=√[9+169]
d=√178
d=13.34 ~13 units
Answer: D) 13
