Plotting Points on a Coordinate Grid

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). It is used to locate points using ordered pairs (x, y).

Front

What are the x-axis and y-axis?

Back

The x-axis is the horizontal line on a coordinate grid, while the y-axis is the vertical line. They intersect at the origin (0,0).

Front

What is the origin in a coordinate grid?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the coordinates (0,0).

Front

How do you identify a point on the y-axis?

Back

A point is on the y-axis if its x-coordinate is 0. For example, (0,7) is on the y-axis.

Front

How do you identify a point on the x-axis?

Back

A point is on the x-axis if its y-coordinate is 0. For example, (7,0) is on the x-axis.

Front

What does it mean to plot a point on a coordinate grid?

Back

To plot a point means to mark its location on the grid using its coordinates (x, y).

Front

What is the difference between horizontal and vertical lines?

Back

Horizontal lines run left to right (parallel to the x-axis), while vertical lines run up and down (parallel to the y-axis).

Front

If two points have the same x-coordinate, how are they positioned on the grid?

Back

If two points have the same x-coordinate, they are positioned vertically aligned on the grid.

Front

If two points have the same y-coordinate, how are they positioned on the grid?

Back

If two points have the same y-coordinate, they are positioned horizontally aligned on the grid.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate grid, written as (x, y).
