Front

What is the slope of a line that is perpendicular to a line with slope m = 3?

Back

The slope of a line that is perpendicular to a line with slope m = 3 is -1/3.

Front

What is the slope-intercept form of the line that passes through the point (5, -4) and is perpendicular to the line represented by y = \frac{5}{2}x + 3?

Back

The equation is y = \frac{-2}{5}x - 2.

Front

Solve the inequality: -4n + 1 > -23. What is the solution set?

Back

The solution set is n < 6.

Front

What is the slope of a line that is parallel to a line with slope m = 4?

Back

The slope of a line that is parallel to a line with slope m = 4 is 4.

Front

Which equation represents a line with a slope of 3 that passes through the point (0, 9)?

Back

The equation is y = 3x + 9.

Front

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

Back

The product of the slopes of two perpendicular lines is -1.

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 = \frac{y2 - y1}{x2 - x1}.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

If a line has a slope of -2, what is the slope of a line parallel to it?

Back

The slope of a line parallel to it is also -2.

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.
