Question

A few locations in the town of Shady Brook are mapped out on the coordinate plane below. Each unit on the grid represents one mile.

Part A: Which two locations shown have the same x-coordinate or y-coordinate? Which coordinates do they share?

Part B: How can the shared coordinate from Part A be used to find the distance between the two locations?

Answer 1

See below in bold.

Explanation:

Part A.

The High School and the Park have the same y-coordinate .

Their coordinates are (-6, 6) and (2, 6).

They share the same y coordinate , y = 6.

Part B.

The distance between the above 2 locations = the difference in their x coordinates.

This is 2 - (-6)

= 2 + 6

= 8 miles.
