writing equations of parallel and perpendicular lines

Front

What is the slope of a line that is parallel to the line represented by the equation y = 3x + 5?

Back

The slope is 3.

Front

What is the slope of a line that is perpendicular to the line represented by the equation y = -rac{1}{4}x + 2?

Back

The slope is 4.

Front

Write the equation of a line parallel to y = 5x - 3 that passes through the point (1, 2).

Back

y = 5x - 3.

Front

If two lines are parallel, what can be said about their slopes?

Back

Their slopes are equal.

Front

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

Back

The slope is -rac{1}{2}.

Front

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

Back

y = -rac{1}{2}x + rac{11}{2}.

Front

What is the relationship between the slopes of two perpendicular lines?

Back

The slopes are opposite reciprocals.

Front

Write the equation of a line parallel to y = -3x + 4 that passes through the point (0, 1).

Back

y = -3x + 1.

Front

What is the slope of a line that is parallel to the x-axis?

Back

The slope is 0.

Front

What is the slope of a line that is perpendicular to the y-axis?

Back

The slope is undefined.
