Question

Eliza uses the point (3, 9) to her home’s location and uses the point (6, 13) to represent the ice cream shop’s location. Each unit on the graph represents 1 mi. How far her home from the ice cream shop? Show your work. Be sure to use the ordered pairs to find the distances! The y-axis scale goes by 2’s, so it can be confusing. Answer:

Answer 1

Use the distance formula:

Distance = sqrt((x2-x1)^2 + (y2-y1)^2)

Distance = sqrt((6-3)^2 + (13-9)^2)

Distance = sqrt(3^2 + 4^2)

Distance = sqrt(9 + 16)

Distance = sqrt(25)

Distance = 5

The problem says every unit = 1 mile so 5 units = 5 miles.

Answer = 5 miles
