Slope, Graphing, and Intercepts Review

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, represented as (0, y).

What is the x-intercept of a graph?

Back

The x-intercept is the point where the graph crosses the x-axis, represented as (x, 0).

Front

How do you find the slope of a line?

Back

The slope (m) is calculated as the change in y divided by the change in x, or m = (y2 - y1) / (x2 - x1).

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

What does a slope of zero mean?

Back

A slope of zero means the line is horizontal and does not rise or fall.

How can you determine the slope from a graph?

Back

To determine the slope from a graph, select two points on the line, find the rise (change in y) and run (change in x), and calculate m = rise/run.
