the x-coordinate of a point where a graph crosses the x-axis

the difference between the terms in an arithmetic sequence

Over equal intervals, the y-values increase by adding or subtracting the same number each time. *Note that the slope in the example would be 3/1= 3

a plane divided into four quadrants by the intersection of the x-axis and the y-axis at the origin

one of four sections into which the coordinate plane is divided

term where it crosses the y-axis

A characteristic or constant factor, limit

arithmatic sequence
