Front

What is the slope of a line perpendicular to the line represented by the equation y = 2x + 4?

Back

-1/2

Front

True or False: Parallel lines have the same slope.

Back

True

Front

If the slopes of two lines are m = -1/3 and m = -1/3, what relationship do these lines have?

Back

Parallel

Front

What is the slope of a line parallel to the line represented by the equation y = 2x + 4?

Back

2

Front

If the slopes of two lines are m = 5 and m = -1/5, what relationship do these lines have?

Back

Perpendicular

Front

Define slope in the context of a linear equation.

Back

Slope is a measure of the steepness of a line, calculated as the change in y over the change in x (rise/run).

Front

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

Back

The product of their slopes is -1.

Front

If a line has a slope of 3, what is the slope of a line parallel to it?

Back

3

Front

If a line has a slope of -4, what is the slope of a line perpendicular to it?

Back

1/4

Front

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

Back

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