Explain how we plot points in exact locations on the coordinate plane.

Locations on the coordinate plane are described as ordered pairs. An ordered pair tells you the location of a point by relating the point's location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair).

Step-by-step explanation:

There are two axes. The x axis is left to right (horizontal). The y axis is bottom to top (vertical).

Step-by-step explanation:

Example positive coordinate: (2,3)

1. The first number in the brackets relates to the x axis.

2. The 2 means move two places to the right, along the x axis.

3. The second number in the brackets relates to the y axis.

4. The 3 moves move three places up, along the y axis.

Example negative coordinate: (-1,-2):

1. Remember the first number in the brackets relates to the x axis.

2. The -1 means move one place, but because there is a minus sign in front of it, this time we move one place to left, along the x axis.

3. The second nimber in the brackets relates to the y axis.

4. The -2 means move teo places, but because there is a minus sign in front of it, this time we move two places down, along the x axis.
