Front

How do you find the slope of a line that goes up from left to right?

Back

The slope is positive.

Front

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

Back

2 (4/2 = 2).

Front

If a line falls 3 units and runs 6 units, what is the slope?

Back

-1/2 (-3/6 = -1/2).

Front

What does a slope of 0 mean?

Back

The line is horizontal.

Front

What does an undefined slope mean?

Back

The line is vertical.

Front

Find the slope of a line that passes through the points (2, 3) and (4, 7).

Back

2 (Rise = 4, Run = 2; 4/2 = 2).

Front

If a line has a slope of -3/2, what does this indicate about its direction?

Back

The line goes down from left to right.
