Plotting Points & Finding Slope

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the horizontal number line called?

Back

x-axis.

Front

What is the vertical number line called?

Back

y-axis.

Front

What are coordinates?

Back

Coordinates are a set of values that show an exact position on a graph, typically written as (x, y).

Front

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

Back

The origin.

Front

What is a positive slope?

Back

A positive slope means that as x increases, y also increases, resulting in an upward line.

Front

What is a negative slope?

Back

A negative slope means that as x increases, y decreases, resulting in a downward line.

Front

What does a slope of zero indicate?

Back

A slope of zero indicates a horizontal line, where y remains constant as x changes.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where x remains constant as y changes.
