Question

City planners are creating a neighborhood map on a coordinate grid. In this coordinate grid, the distance between each gridline represents 1 mile. The park is located at (-7, 3) and the farmer's market is located at (-7, -6). How many miles apart are the park and the farmer's market?

Answer 1

x1 = -7
x2 = -7
y1 = 3
y2 = -6

Distance formula:
Square root of (x2-x1)^2 + (y2-y1)^2
Square root of (-7+7)^2 + (-6-3)^2
Square root of 0^2 + -9^2
Square root of 0 + 81
Square root of 81
9 miles

Check: x coordinates are the same, y coordinates are different.
3 - (-6) = 3 + 6 = 9 :)
