Coordinate Graph Easy

x-axis

• the axis along which values of x are measured (horizontal)

• the axis along which values of x are measure (vertical)

y-axis

• the axis along which values of y are measure (vertical)

• the axis along which values of x are measured (horizontal)

Quadrant

• The section created by the dissection of the coordinate plane by the x and y axis. Roman numerals are used to notate the quadrants.

• Quadrant I, Quadrant II, Quadrant III and Quadrant IV

• Start in the top right and follow counter clockwise

• All of the above

Quadrant I or Q I

• Top right section with the (+,+) coordinates.

• Top left section with the (-,+) coordinates.

• Bottom left section with the (-,-) coordinates.

• Bottom right section with the (+,-) coordinates.

Quadrant II or Q II

• Top right section with the (+,+) coordinates.

• Top left section with the (-,+) coordinates.

• Bottom left section with the (-,-) coordinates.

• Bottom right section with the (+,-) coordinates.

Quadrant III

• Top right section with the (+,+) coordinates.

• Top left section with the (-,+) coordinates.

• Bottom left section with the (-,-) coordinates.

• Bottom right section with the (+,-) coordinates.

Quadrant IV or QIV

• Top right section with the (+,+) coordinates.

• Top left section with the (-,+) coordinates.

• Bottom left section with the (-,-) coordinates.

• Bottom right section with the (+,-) coordinates.

x-coordinate

• the x-value in an ordered pair. It is the first value.

• (x,y)

Y-Coordinate

• The y-value in an ordered pair.

• Where a line cross the y-axis

• A

• B

• C

• D
