What is the slope of a line that is perpendicular to a line with slope m = 1/9?

Back

The slope of a line that is perpendicular to a line with slope m = 1/9 is m = -9.

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

What is the slope-intercept form of a line?

Back

Front

If a line has a slope of 5, 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 5 is also 5.

Front

Back

Front

What is the equation of the perpendicular bisector of a segment?

Back

The equation of the perpendicular bisector can be found using the midpoint of the segment and the negative reciprocal of the slope of the segment.

Front

How do you find the slope between two points (x_1, y_1) and (x_2, y_2)?

Back

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

If a line has the equation y = 5x - 3, what is the equation of a line parallel to it that passes through (0, 4)?

Back

The equation of the line parallel to y = 5x - 3 that passes through (0, 4) is y = 5x + 4.
