Question

If someone could answer these two questions, that would be wonderful:

1. Describe how an ordered pair represents a point on a coordinate plane. Include the terms x-coordinate, y-coordinate, and origin in your answer.

2. Give the coordinates of one point in each of the four quadrants, one point on the x-axis, and one point on the y-axis

Answer 1

1. An ordered pair is a pair of numbers in parentheses, separated by a comma, which indicates the distance of a point from the origin. The first number represents the x-coordinate (where it is from side-to-side), and the second number represents the y-coordinate (where it is from up and down).

2. The four quadrants of the basic plane are listed in this order:

II | I
|
=========
|
III | IV

A point in the first quadrant (I) could be (5, 10), since that means that you would be moving right 5 and up 10.

A point in the second quadrant (II) could be (-3, 6), since that means that you would be moving left 3 and up 6.

A point in the third quadrant (III) could be (-7, -1) since that means that you would be moving left 7 and down 1.

A point in the fourth quadrant (IV) could be (2, -6) since that means that you would be moving right 2 and down 6.

A point on the x-axis could be (9, 0) since that means that we are moving right 9 and making no vertical movement.

A point on the y-axis could be (0, 4), since that means that we are going up 4 and making no horizontal movement.

Hope that helped! =)
