Points on a Coordinate Plane

A coordinate plane is a graph with a horizontal number line, called the x-axis, and a vertical number line, called the y-axis. Points on a coordinate plane are identified by their distance on each of the axes.

The x-axis extends from left to right. The y-axis goes from bottom to top.

The origin is the zero point on both number lines, and the point where the x-axis and y-axis intersect.

Which of these ordered pairs describes the origin?

• (X,Y)

• (0,0)

• (0,1)

• (1,1)

Coordinates are given as ordered pairs, with the coordinate on the x-axis first and the y-axis second. If both numbers are positive, the coordinate is in the first quadrant. If the first is negative and the second is positive, the coordinate is in the second quadrant. If both numbers are negative, the coordinate is in the third quadrant. If the first number is positive and the second is negative, the coordinate is in the fourth quadrant. The ordered pair (2,1) refers to a point that is 2 away from 0 on the x-axis and 1 away from 0 on the y-axis. If is in the first quadrant.

Which of these ordered pairs describes a coordinate in the third quadrant?

• (3,5(

• (-3,5)

• (-3,-5)

• (3,-5)

If the treasure is at (3,6), then how far do you need to move on the x-axis to reach this location? How far on the y-axis?

• 3 units right on the x-axis and 6 units up on the y-axis.

• 6 units right on the x-axis and 3 units up on the y-axis

• 3 units left on the x-axis and 6 units down on the y-axis

• 3 units left on the x-axis and 6 units up on the y-axis
