Coordinate Movement and Grid Concepts

Maria Miller introduces the concept of a coordinate grid, focusing on the first quadrant. She explains how to identify and plot points using x and y coordinates. The lesson includes drawing a triangle and moving it on the grid, highlighting how movements affect coordinates. The video aims to help viewers understand the basics of coordinate systems and how to manipulate shapes within them.

What is a coordinate grid?

• A grid without any lines

• A grid with only horizontal lines

• A grid that has coordinates on it

• A grid with only vertical lines

What is the purpose of the numbers on a coordinate grid?

• To decorate the grid

• To define the location of points

• To confuse the user

• To make the grid colorful

What is the horizontal line on a coordinate grid called?

• Y-axis

• Z-axis

• X-axis

• W-axis

What is the vertical line on a coordinate grid called?

• X-axis

• W-axis

• Y-axis

• Z-axis

How do you find the x-coordinate of a point?

• Look at the y-axis

• Look at the z-axis

• Look at the x-axis

• Look at the w-axis

How do you find the y-coordinate of a point?

• Look at the w-axis

• Look at the y-axis

• Look at the z-axis

• Look at the x-axis

What are the coordinates of point A if it is located at (4, 3)?

• (3, 4)

• (2, 5)

• (5, 2)

• (4, 3)

What is the x-coordinate of point B if it is located at (9, 5)?

• 5

• 6

• 9

• 4

How do you plot the point (1, 7) on the grid?

• Move 7 units on the x-axis, then 1 unit up

• Move 1 unit on the x-axis, then 7 units up

• Move 7 units on the y-axis, then 1 unit right

• Move 1 unit on the y-axis, then 7 units right
