Do Now Write down 4 things that you know about a COORDINATE GRID

 Name the parts of a coordinate plane  Locate points on a coordinate plane  Use x- and y- values

 X-axis  Y-axis  Origin  X-coordinate  Y-coordinate  Ordered Pair

X-axis Horizontal (left to right/ west to east) Y-axis Vertical (up to down/ north to south) Origin (0, 0) Point where x and y meet to form a right angle

X-coordinate Point right or left of the origin Y-coordinate Point up or down of the origin Order pairs Two numbers that tell where the x-coordinate and y-coordinate form the point

 Axes  Coordinates  Coordinate Plane  Quadrants

Axes Two perpendicular number lines that meet at Their zero point Coordinates Two numbers used to locate a point on a coordinate plane Coordinate Plane A region formed by a pair of axes Quadrants Four regions where the coordinate plane is divided.

 Horizontal axis (x-axis)  Vertical axis (y-axis)  Origin  Four Quadrants

 Quadrant I (+, +)  Quadrant II (-, +)  Quadrant III (-, - )  Quadrant IV (+, -)

 (x, y)  X = horizontal axis  Y = vertical axis

Two numbers written in a certain order. Usually written in parentheses like this: (4,5) Can be used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second.

 (4, 5)  What quadrant would this be located?  Do I start with my x-axis or y-axis?  What number is on my x-axis and y-axis?

 Quadrant I  Positive, positive  Start with my x-axis  4 is my x and 5 is my y

 ( -6, 3)  (-8, -8)  (4, -3)  (5, 2)

 (-6, 3) Quadrant II  (-8, -8) Quadrant III  (4, -3) Quadrant IV  (5, 2) Quadrant I

 3 east, 4 north and 3 east, 5 south  11 west, 18 north and 11 west, 27 south

 Is the point (2, 5) on the coordinate plane the same as the point (5,2)?  Explain your answer.
