Front

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

Back

The line is decreasing from left to right.

Front

Calculate the slope between the points (2, 3) and (5, 11).

Back

Slope = (y2 - y1) / (x2 - x1) = (11 - 3) / (5 - 2) = 8/3.

Front

What does a positive slope indicate about a line?

Back

The line rises as it moves from left to right.
