Lesson 2: Coordinate plane word problems

# Coordinate plane graphing word problem

The video dives into the concept of using a coordinate plane to solve real-world problems. It emphasizes how to plot points on the plane and interpret their values, and how to calculate the distance between two points by counting blocks in both the horizontal and vertical directions.

• How do you remember which axis goes first? Is it Y axis or X axis?
• Chloe you know because the X axis comes first and the Y axis comes next like here's an example (9,8)so the 9 is the X axis and the 8 is the Y axis so there you go :3 :>
• At 0.:25 what does "blocks" mean? (Serious question)
• blocks mean streets in the example that Sal uses in the video
• assume you have 5.7 * 14.73. First number has decimal after 1st digit, second number has after 2 digits.
You can directly multiply without seeing decimal and put decimal after third number (1+2) from left to the answer. You may get proof if you write it as
(57/10) * (1473/100) = (57*1473) / (10*100) = 83961/1000 = 83.961
