Coordinate Plane Concepts and Terminology

Mr. Richards teaches graphing in four quadrants, covering key terms like ordered pairs, origin, x-axis, and y-axis. He demonstrates naming ordered pairs and graphing points in different quadrants. The lesson includes a classroom quiz game where students solve a problem using a table of values and graphing, reinforcing the concepts of ordered pairs and equations.

What is the main focus of today's lesson?

• Graphing in the four quadrants

• Learning about angles

• Solving algebraic equations

• Understanding fractions

Which axis is vertical on the coordinate plane?

• X-axis

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

• Origin

• Vertex

• Intersection

• Midpoint

In an ordered pair, which coordinate is listed first?

• Y-coordinate

• Z-coordinate
