Front

If the slope of a line is -3, what does this indicate about the line's direction?

Back

The line decreases as it moves from left to right.

Front

Convert the point-slope form equation y - 2 = 3(x - 1) to slope-intercept form.

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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