What is a coordinate on a number line?

As you remember from pre-algebra a coordinate plane is a two-dimensional number line where the vertical line is called the y-axis and the horizontal is called the x-axis. These lines are perpendicular and intersect at their zero points. This point is called the origin. The axes divide the plane into four quadrants.

Also to know is, how do you plot a point on a coordinate plane?

Graphing a Single Point. Start at (0, 0), or the origin. Just go to (0, 0), which is the intersection of the x and y axes, right in the center of the coordinate plane. Move over x units to the right or left.

What are coordinates of a point?

The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis. The coordinates of a given point represent how far along each axis the point is located.

What is used to locate a point on a coordinate plane?

The point where the x and y axes intersect is called the origin. The origin is located at zero on the x axis and zero on the y axis. We can locate any point on the coordinate plane using an ordered pair of numbers like the example shown here, the ordered pair 4 and 2 (point P).
