1A- Slope-Graphing Points on a Coordinate Planes

Front

What is the definition of a coordinate plane?

Back

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

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point on a coordinate plane, typically written in the form (x, y), where x is the horizontal position and y is the vertical position.

Front

How do you identify the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair (x, y) and represents the horizontal position of the point on the coordinate plane.

Front

How do you identify the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair (x, y) and represents the vertical position of the point on the coordinate plane.

Front

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

Back

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

Front

What is the significance of negative coordinates in a coordinate plane?

Back

Negative coordinates indicate positions that are to the left of the origin on the x-axis or below the origin on the y-axis.

Front

How do you plot the point (2, 3) on a coordinate plane?

Back

To plot the point (2, 3), start at the origin (0, 0), move 2 units to the right along the x-axis, and then move 3 units up along the y-axis.

Front

What is the purpose of labeling points with letters (e.g., A, B, C) on a coordinate plane?

Back

Labeling points with letters helps to easily identify and reference specific points when discussing or solving problems related to the coordinate plane.

Front

How can you determine the coordinates of a point on a graph?

Back

To determine the coordinates of a point on a graph, locate the point's position relative to the x-axis and y-axis, and read the corresponding values.

Front

What is the relationship between the coordinates of a point and its position on the coordinate plane?

Back

The coordinates of a point directly indicate its position on the coordinate plane, with the x-coordinate determining horizontal placement and the y-coordinate determining vertical placement.
