In this lesson our instructor talks about graphing in the coordinate plane. She talks about coordinate plane, y-axis, x-axis, quadrants origin, ordered pair, x-coordinate, and y-coordinate. She talks about labeling vocabulary and graphing points on a coordinate plane. Four extra examples round up this lesson.

i dont understand the vocab and this question(i mean extra example 1and2)

Graphing in the Coordinate Plane

Coordinate Plane: grid formed by intersection of two number lines

y-axis: a vertical number line

x-axis: a horizontal number line

Quadrants: the axes divide the plane into four quadrants

Origin: where the axes intersect

Ordered Pair: (x,y), gives the coordinates of a point‘s location

x-coordinate: the position to the right or left of the y-axis (x, y)

y-coordinate: the position above or below the x-axis (x, y)

Remember that in an ordered pair, the x term always come before the y: (x, y). An easy way to remember this is that the letters are in alphabetical order.
