Coordinate Graphing

Front

What is a coordinate graph?

Back

A coordinate graph is a two-dimensional plane formed by the intersection of a horizontal axis (x-axis) and a vertical axis (y-axis), used to plot points, lines, and curves.

Front

What does an ordered pair represent in coordinate graphing?

Back

An ordered pair represents a specific point on a coordinate graph, where the first number is the x-coordinate and the second number is the y-coordinate.

Front

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

Back

The x-value in an ordered pair is the first number listed, which indicates the horizontal position on the graph.

Front

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

Back

The y-value in an ordered pair is the second number listed, which indicates the vertical position on the graph.

Front

What is the significance of the origin in a coordinate graph?

Back

The origin is the point (0, 0) on a coordinate graph where the x-axis and y-axis intersect, serving as the reference point for all other points.

Front

What are the four quadrants in a coordinate graph?

Back

The four quadrants are the sections of the coordinate plane divided by the x-axis and y-axis: Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), Quadrant IV (positive x, negative y).

Front

How do you plot a point given an ordered pair?

Back

To plot a point given an ordered pair (x, y), start at the origin, move x units along the x-axis, and then move y units up (if positive) or down (if negative) to locate the point.

Front

What is the distance formula used for in coordinate graphing?

Back

The distance formula is used to calculate the distance between two points in a coordinate plane, given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the midpoint formula in coordinate graphing?

Back

The midpoint formula is used to find the midpoint between two points (x1, y1) and (x2, y2), given by the formula: M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What does it mean for points to be collinear?

Back

Points are collinear if they lie on the same straight line.
