Intro to Graphing

Front

What is the y-axis in a graph?

Back

The y-axis is the vertical line on a graph that represents the range of values for the dependent variable.

Front

What is an ordered pair in coordinate geometry?

Back

An ordered pair is a pair of numbers used to represent a point on a graph, typically written in the form (x, y).

Front

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

Back

The x-coordinate is the first number in an ordered pair, indicating the position along the horizontal axis.

Front

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

Back

The y-coordinate is the second number in an ordered pair, indicating the position along the vertical axis.

Front

What does the point (6, 8) represent on a graph?

Back

The point (6, 8) represents a location where the x-coordinate is 6 and the y-coordinate is 8.

Front

What is the significance of the origin in a graph?

Back

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

Front

What does it mean for a point to be on the y-axis?

Back

A point is on the y-axis if its x-coordinate is 0, meaning it lies directly above or below the origin.

Front

How do you plot the point (-4, -4) on a graph?

Back

To plot (-4, -4), move 4 units left on the x-axis and 4 units down on the y-axis from the origin.

Front

What is the relationship between the coordinates of point E, (-3, 0)?

Back

Point E has an x-coordinate of -3 and a y-coordinate of 0, meaning it lies on the x-axis.

Front

What does it mean if two points have the same x-coordinate?

Back

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