Writing equations of lines parallel and perpendicular

Front

What is the slope of a line that is perpendicular to a line with a slope of -2?

Back

The slope of a line that is perpendicular to a line with slope -2 is \frac{1}{2}.

Front

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

Back

The slope of a line that is parallel to a line with slope 3 is also 3.

Front

Write the equation of a line parallel to y = 4x + 1 that passes through the point (2, 5).

Back

y = 4x - 3.

Front

Write the equation of a line perpendicular to y = -\frac{1}{3}x + 2 that passes through the point (1, 4).

Back

y = 3x + 1.

Front

What is the general form of the equation of a line?

Back

The general form of the equation of a line is Ax + By + C = 0.

Front

How do you find the y-intercept of a line given its equation in slope-intercept form?

Back

The y-intercept is the value of y when x = 0, represented as (0, b) in the equation y = mx + b.

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 in slope-intercept form given a slope of -2 and a y-intercept of 3.

Back

y = -2x + 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.
