Understanding Coordinate Plane Concepts

This video tutorial covers graphing points in the coordinate plane, explaining the four quadrants, the x-axis and y-axis, and how to plot points. It discusses ordered pairs, graphing points on axes, and labeling them. The lesson also covers reading scales on axes, emphasizing the importance of understanding increments. The tutorial concludes with a summary and a preview of the next lesson.

What are the two number lines called in a coordinate plane?

• x-axis and z-axis

• x-axis and y-axis

• y-axis and z-axis

• a-axis and b-axis

How many quadrants are there in a coordinate plane?

• Two

• Five

• Three

• Four

What is the term used for graphing a point on the coordinate plane?

• Marking a point

• Plotting a point

• Sketching a point

• Drawing a point

If a point is located on one of the axes, what must be true about one of its coordinates?

• Both coordinates are negative

• Both coordinates are positive

• Both coordinates are non-zero

• One of the coordinates must be zero

How are ordered pairs written in the coordinate plane?

• With both coordinates separated by a semicolon

• With the x-coordinate first

• With the y-coordinate first

• With both coordinates in brackets

What does each square on the coordinate plane represent?

• Two units

• One unit

• Half a unit

• Ten units

What is the ordered pair for a point located five units to the right and seven units up from the origin?

• (5, 7)

• (-5, 7)

• (7, 5)

• (5, -7)

When graphing with a scale where each unit is equal to 10, what is the x-coordinate of a point three units over?

• 40

• 30

• 10

• 20

If a coordinate plane is labeled in increments of 20, what is the value of each unit?

• 20

• 10

• 5

• 15

What should you pay attention to when graphing points on a coordinate plane with different scales?

• The shape of the points

• The size of the graph paper

• The labels on the axes

• The color of the axes
