Understanding Coordinate Grid Movements

The video tutorial explains how to plot points on a coordinate grid, using examples of plotting (4, 3) and (8, 2). It highlights common mistakes made by Jazelle and Lucia, who incorrectly plotted points by confusing the x and y coordinates. The tutorial emphasizes the correct method of moving along the x-axis first and then the y-axis, and it provides a step-by-step analysis of the errors to reinforce understanding.

What is the first step in plotting a point on a coordinate grid?

• Move left along the x-axis

• Move up along the y-axis

• Move right along the x-axis

• Move down along the y-axis

In a coordinate grid, what does the first number in an ordered pair represent?

• Vertical movement

• Horizontal movement

• Diagonal movement

• No movement

When plotting the point (4, 3), how many units should you move up after moving right?

• 2 units

• 3 units

• 5 units

• 4 units

What is the correct sequence of movements for plotting (4, 3)?

• Right then up

• Down then right

• Up then right

• Right then down

What mistake did Jazelle make when plotting the point (4, 3)?

• Moved up instead of down

• Moved left instead of right

• Moved down instead of up

• Moved right instead of left

What is the correct movement for the x-coordinate when plotting (8, 2)?

• 8 units up

• 8 units right

• 8 units down

• 8 units left

How many units should you move up when plotting the point (8, 2) after moving right?

• 2 units

• 1 unit

• 4 units

• 3 units

What mistake did Lucia make when plotting the point (8, 2)?

• Moved right instead of left

• Moved down instead of up

• Moved left instead of right

• Confused the x and y coordinates

What is the role of the y-coordinate in an ordered pair?

• Determines no movement

• Determines vertical movement

• Determines horizontal movement

• Determines diagonal movement

What should you do if you confuse the x and y coordinates when plotting a point?

• Move diagonally

• Start over and plot correctly

• Ignore the mistake

• Plot the point in reverse
