In this lesson our instructor talks about the coordinate plane. She talks bout the coordinate system, quadrants, origin, ordered pair and an example of writing coordinates. She discusses graphing coordinate plane and collinear. Four extra example videos round up this lesson.
The x-axis and y-axis split the coordinate plane into 4 quadrants
The origin is at (0,0)
Collinear: Points that lie on the same line
