Finding Slope from a Graph

Front

What type of slope does a line that goes down from left to right have?

Back

Negative

Front

What is the slope?

Back

The ratio of rise over run, vertical change over horizontal change, or change in y over change in x.

Front

What type of slope does a line that goes up from left to right have?

Back

Positive

Front

What is the slope of a horizontal line?

Back

0

Front

What is the slope of a vertical line?

Back

Undefined

Front

How do you calculate the slope of a line?

Back

Slope = (change in y) / (change in x) or rise/run.

Front

If a line rises 3 units and runs 1 unit, what is the slope?

Back

3/1 or 3.

Front

If a line falls 2 units and runs 4 units, what is the slope?

Back

-2/4 or -1/2.

Front

What does a slope of 1 indicate?

Back

For every 1 unit increase in x, y increases by 1 unit.

Front

What does a slope of -1 indicate?

Back

For every 1 unit increase in x, y decreases by 1 unit.
