Parallel and Perpendicular Slopes

Front

What is the slope of a line that is perpendicular to a line with a slope of -6?

Back

The slope of the perpendicular line is 1/6.

Front

What is the slope-intercept form of a line with a slope of 2 and a y-intercept of 3?

Back

The equation is y = 2x + 3.

Front

If two lines have slopes of -2/3 and 3/2, what is their relationship?

Back

The lines are perpendicular.

Front

What is the slope of a line that is perpendicular to y = 2x - 7?

Back

The slope of the perpendicular line is -1/2.

Front

What is the slope of a line that is parallel to y = -6x + 2?

Back

The slope of the parallel line is -6.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and 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

What is the slope of the line represented by the equation y = 2?

Back

The slope is 0, indicating a horizontal line.

Front

What is the slope of the line represented by the equation x = 2?

Back

The slope is undefined, indicating a vertical line.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).
