Q

Define “Coordinate Plane”

A
  1. The 2 dimensional plane, or the x-y plane.
  2. A 2 dimensional object formed by two number lines, one horizontal and one vertical (so that they intersect at right angles)

Q

Define “Ordered Pair”

A
  1. The two coordinates used to identify a point on a coordinate plane
  2. Ordered pairs are often written in the form (x,y), with the x axis coordinate first and the y-axis coordinate second

Q

Define “Slope”

A
  1. The “Rise over run” or change in y over the change in x
  2. The quantity of the vertical change in y-values divided by the horizontal change in x-values
