Coordinate Grid

Front

What is a coordinate grid?

Back

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

Front

What are the coordinates of a point?

Back

Coordinates of a point are a pair of numbers (x, y) that define its position on a coordinate grid, where 'x' represents the horizontal position and 'y' represents the vertical position.

Front

How do you plot the point (3, 5) on a coordinate grid?

Back

To plot the point (3, 5), move 3 units to the right along the X-axis and 5 units up along the Y-axis.

Front

What is the X-axis?

Back

The X-axis is the horizontal line in a coordinate grid where the Y-coordinate is zero.

Front

What is the Y-axis?

Back

The Y-axis is the vertical line in a coordinate grid where the X-coordinate is zero.

Front

What does the point (0, 0) represent on a coordinate grid?

Back

The point (0, 0) is known as the origin, where the X-axis and Y-axis intersect.

Front

How do you identify the quadrant of a point (x, y)?

Back

The quadrant of a point is determined by the signs of x and y: Quadrant I (x>0, y>0), Quadrant II (x<0, y>0), Quadrant III (x<0, y<0), Quadrant IV (x>0, y<0).

Front

What is the distance between the points (2, 3) and (2, 7)?

Back

The distance between the points (2, 3) and (2, 7) is 4 units, measured vertically along the Y-axis.

Front

What is the slope of a line between the points (1, 2) and (3, 6)?

Back

The slope of the line is calculated as (y2 - y1) / (x2 - x1) = (6 - 2) / (3 - 1) = 4 / 2 = 2.

Front

What does it mean for a point to be in Quadrant II?

Back

A point in Quadrant II has a negative x-coordinate and a positive y-coordinate.
