Unit 7 FC 7 parallel and perpendicular slope

Front

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

Back

-1/2

Front

What do the slopes m = -1/3 and m = -1/3 indicate about the two lines?

Back

Parallel

Front

What do the slopes m = 5 and m = -1/5 indicate about the two lines?

Back

Perpendicular

Front

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

Back

2

Front

True or False: Parallel lines have the same slope.

Back

True

Front

Define slope in the context of a linear equation.

Back

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

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 that is perpendicular to it?

Back

-1/3

Front

If two lines have slopes of m1 and m2, what condition must be met for them to be parallel?

Back

m1 = m2.

Front

If two lines have slopes of m1 and m2, what condition must be met for them to be perpendicular?

Back

m1 * m2 = -1.
