Coordinate plane

a plane formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis

x-axis

the horizontal axis on a coordinate plane

y-axis

the vertical axis on a coordinate plane

origin

the point where the x-axis and y-axis intersect on the coordinate plane; (0,0)

quadrant

the x- and y-axes divide the coordinate plane into four regions. Each region is called a quadrant

Ordered pair

a pair of numbers that can be used to locate a point on a coordinate plane

negative slope

a line that falls from left to right

positive slope

a line that falls from right to left

constant rate of change

describes changes of the same amount during equal intervals

variable rate of change

describes changes of a different amount during equal intervals

rise

vertical change of a line

run

horizontal change of a line
