Front

What is the definition of slope?

Back

The ratio of the rise (change in y) to the run (change in x) between two points on a line.

Front

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

Back

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

Front

What is the formula for the slope-intercept form of a line?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Their slopes are opposite reciprocals.
