Parallel and Perpendicular equations

Front

What is the slope of a line that is perpendicular to the line with slope 3?

Back

The slope of a line that is perpendicular to a line with slope 3 is -1/3 (the opposite reciprocal).

Front

What is the slope of a line that is parallel to the line with slope 5?

Back

The slope of a line that is parallel to a line with slope 5 is also 5.

Front

Write the equation of a line that passes through the point (0, 0) and has a slope of 2.

Back

y = 2x.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

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

Front

Write the equation of a line that is parallel to the line y = -x + 4 and passes through the point (1, 2).

Back

y = -x + 3.

Front

If a line has a slope of 0, what type of line is it?

Back

A line with a slope of 0 is a horizontal line.

Front

If a line has an undefined slope, what type of line is it?

Back

A line with an undefined slope is a vertical line.

Front

Determine if the lines y = 2x + 1 and y = 2x - 3 are parallel, perpendicular, or neither.

Back

The lines are parallel because they have the same slope of 2.

Front

Write the equation of a line that is perpendicular to y = 1/2x + 3 and passes through the point (2, 1).

Back

y = -2x + 5.
