Front

How do you calculate the slope of a line?

Back

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

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What is the slope of the line represented by the points (2, 3) and (4, 1)?

Back

Slope = (1 - 3) / (4 - 2) = -2/2 = -1.

Front

What is the slope of the line represented by the points (1, 2) and (1, 5)?

Back

Undefined (vertical line).

Front

What is the slope of the line represented by the points (0, 0) and (3, 3)?

Back

Slope = (3 - 0) / (3 - 0) = 1.

Front

What is the slope of the line represented by the points (2, 4) and (5, 4)?

Back

0 (horizontal line).

Front

What does 'rise over run' mean in the context of slope?

Back

It refers to the vertical change (rise) divided by the horizontal change (run) between two points on a line.
