Coordinates in the First Quadrant

Types of axis

x-axis and y-axis

X-axis

Horizontal axis

Y-axis

Vertical axis

Coordinates

( x , y )

Example of coordinates

( 3 , 7 ), ( 2 , 5 ), ( 9 , 4 )

Point at x-axis

( x , 0 )

Point at y-axis

( 0 , y )

Example of point at x-axis

( 4 , 0 ) therefore the value of point x is 4

Example of point at y-axis

( 0 , 5 ) therefore the value of point y is 5

Method to mark coordinates of points ( 4 , 2 )

Move 4 units to the right and 2 units up from the origin. Mark the point ( 4 , 2 )
