Opposite reciprocals.

Front

What is the equation of a horizontal line at y = -4?

Back

y = -4

Front

What are the slopes of parallel lines?

Back

Front

Find the equation of the line in slope-intercept form with slope m = 3 through the point (2, -5).

Back

y = 3x - 11

Front

What is the slope-intercept form of a line?

Back

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

Front

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

Back

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

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.

Front

What is the y-intercept of the line y = 2x + 3?

Back

The y-intercept is 3.
