Writing Equations of parallel and perpendicular lines

Front

What is the slope of two parallel lines?

Back

The slope of two parallel lines is the same.

Front

What is the slope of two perpendicular lines?

Back

The slopes of two perpendicular lines are opposite reciprocals.

Front

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

Back

y = 2x - 5

Front

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

Back

y = \frac{1}{2}x + 2

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 slope from the equation of a line in slope-intercept form?

Back

In slope-intercept form (y = mx + b), the slope is represented by m.

Front

What does the y-intercept represent in the equation of a line?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

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

Back

y = 3x + 2

Front

What is the slope of the line represented by the equation y = 3x + 1?

Back

The slope of the line is 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.
