Finding Slope from points, graph, table

Front

What is the formula to find the slope (m) between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a positive slope indicate about a line on a graph?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line on a graph?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If the slope of a line is 2, what does this mean in terms of rise over run?

Back

For every 2 units the line rises, it runs 1 unit to the right.

Front

How do you find the slope from a table of values?

Back

Choose two points from the table, (x1, y1) and (x2, y2), and use the slope formula m = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line that passes through the points (1, 3) and (4, 9)?

Back

The slope is 2.

Front

What is the slope of the line that passes through the points (2, 5) and (2, 8)?

Back

The slope is undefined.

Front

What is the slope of the line that passes through the points (0, 0) and (5, 10)?

Back

The slope is 2.
