Front

How do you calculate the slope between 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.

If two lines have the same slope, what can be said about them?

Back

They are parallel.

Front

If two lines have slopes that are negative reciprocals of each other, what can be said about them?
