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
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
