Keystone Module 2

Front

What is a function in mathematics?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

How do you determine if a set of ordered pairs is a function?

Back

A set of ordered pairs is a function if no two different pairs have the same first element (x-coordinate).

Front

What does the slope of a line represent in a graph?

Back

The slope represents the rate of change of the y-coordinate with respect to the x-coordinate, indicating how steep the line is.

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph intersects the y-axis, indicating the value of y when x is 0.

Front

How can you find the height of an airplane at a given time based on a graph?

Back

You can find the height by locating the corresponding y-value for the given x-value on the graph.

Front

What does a linear relationship look like on a graph?

Back

A linear relationship appears as a straight line on a graph, indicating a constant rate of change.

Front

What is the meaning of average speed in a distance-time graph?

Back

Average speed is the total distance traveled divided by the total time taken, represented by the slope of the line on a distance-time graph.

Front

How do you interpret a table of values in relation to a graph?

Back

A table of values can be used to plot points on a graph, showing the relationship between the x and y coordinates.

Front

What is the significance of the coordinates (x, y) in a graph?

Back

The coordinates (x, y) represent a specific point on the graph, where x is the horizontal position and y is the vertical position.
