Exploring Coordinate Grids in Lessons 20, 28, & 29

The video tutorial introduces the coordinate plane, explaining its components like the x-axis, y-axis, and origin. It demonstrates how to graph points using ordered pairs and solve story problems using a coordinate grid. The tutorial also covers calculating distances between points and identifying common axes. Additionally, it explores cost comparisons of model vehicles using ordered pairs, highlighting patterns and rules in data representation.

What is the name of the point where the x-axis and y-axis intersect?

• Origin

• Axis

• Intersection

• Coordinate

Which axis is horizontal on a coordinate grid?

• None

• z-axis

• x-axis

• y-axis

In an ordered pair (x, y), what does the first number represent?

• None

• y-coordinate

• x-coordinate

• Point label

If a point is labeled as (4, 3) on a coordinate grid, how many units up is it from the x-axis?

• 7 units

• 4 units

• 1 unit

• 3 units

What is the ordered pair for the snack stand in the state fair layout story?

• (3, 2)

• (1, 4)

• (4, 1)

• (2, 3)

How many units do you move right from the origin to reach the snack stand?

• 4 units

• 3 units

• 2 units

• 1 unit

What common axis do face painting and the book sale share?

• Neither

• Both

• y-axis

• x-axis

How many units is the distance from the ring toss to the book sale?

• 2 units

• 1 unit

What is the rule for the cost of planes in terms of the number of planes bought?

• Multiply by 4

• Add 4

• Add 2

• Multiply by 2

If the cost of a boat is twice that of a plane, what is the relationship between their costs?

• Boat cost = Plane cost * 2

• Boat cost = Plane cost + 2

• Boat cost = Plane cost - 2

• Boat cost = Plane cost / 2
