Front

How do you calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

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 equation y = -1/2x + 4?

Back

-1/2

Front

If a line has a slope of 3, what does this mean in terms of rise over run?

Back

For every 3 units up (rise), the line goes 1 unit to the right (run).
