Let’s review some vocabulary!
Coordinate plane – the plane containing the x-axis and the y-axis
x-axis - the horizontal number line found on the coordinate plane
y-axis – the vertical number line found on the coordinate plane
quadrant - one of four sections into which the coordinate plane is divided
origin - the point where the x-axis and y-axis meet. (0,0)
coordinates - a pair of numbers used to show the exact position of a point on a
graph
quadrant I - the quadrant where all the x-coordinates and y-coordinates are
positive. (+, +)
quadrant II - the quadrant where all the x-coordinates and y-coordinates are
positive. (-, +)
quadrant III - the quadrant where all the x-coordinates and y-coordinates are
positive. (-, -)
quadrant IV - the quadrant where all the x-coordinates and y-coordinates are
positive. (+, -)
