Front

A line has a slope of 2/3. What is the slope of a perpendicular line?

Back

-3/2

Front

Which two equations below are perpendicular? y = 3x - 4 and y = -1/3x - 2

Back

These lines are perpendicular because the product of their slopes is -1.

Back

-1 ≤ x ≤ 3

Front

What is the definition of a vertical line?

Back

A vertical line is a line that goes straight up and down and has an undefined slope.

Front

What is the definition of a horizontal line?

Back

A horizontal line is a line that goes straight across and has a slope of 0.

Front

What is the slope-intercept form of a line?

Back

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

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
