Front

If a line has a slope of 2, what is the slope of a line that is parallel to it?

Back

The slope of a line that is parallel to a line with slope 2 is also 2.

Front

If a line has a slope of -1/4, what is the slope of a line that is perpendicular to it?

Back

Front

What is the slope-intercept form of a line?

Back

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept.

Front

How can you determine if two lines are parallel from their equations?

Back

Two lines are parallel if they have the same slope.

Front

How can you determine if two lines are perpendicular from their equations?

Back

Two lines are perpendicular if the product of their slopes is -1.
