Finding the Shortest Distance on a Coordinate Plane

This video tutorial teaches how to determine the shortest distance between two points using a coordinate plane. It covers movement and direction on the plane, provides practical examples like calculating distances from a metro station to nearby stores, and compares distances from different houses to a school. The lesson also explores optimizing routes for picking up friends, emphasizing the importance of counting units and choosing efficient paths. The tutorial concludes by reinforcing the skills learned in determining shortest distances.

How do you determine the distance between two points on a coordinate plane?

• By measuring the angle between them

• By counting the number of units moved

• By estimating the distance visually

• By using a ruler

If you are at the metro and want to reach the closest location, which one should you choose?

• The pharmacy, because it is 6 blocks away

• The grocery store, because it is 5 blocks away

• The pharmacy, because it looks closer

• The grocery store, because it is 6 blocks away

Who lives closer to the school?

• The narrator

• The school is equidistant from both

• The narrator's friend

• Both live at the same distance

What is the shortest route for picking up friends before heading to school?

• Start with the closest friend and move outward

• Start with the farthest friend and move inward

• Start with the friend closest to school

• Pick up friends randomly

Why is it beneficial to avoid backtracking when planning a route?

• It allows for more stops along the way

• It ensures you visit each location twice

• It makes the journey more scenic

• It saves time and reduces the total distance traveled
