Asked by Tim

A grid shows the positions of a subway stop and your house. The subway stop is located at (0,-1), and your house is located at (-7,-4). What is the distance, to the nearest unit, between your house and the subway stop?
10 units
58 units
8 units
6 units
Answered by oobleck
the distance is, per the usual formula,
√((-7-0)^2 + (-4+1)^2) = √(7^2+3^2) = √58 = 7.6
so, round up to 8
