Back

Slope

Front

If two lines are parallel, what can you say about their slopes?

Back

Their slopes are equal.

Front

If two lines are perpendicular, what is the relationship between their slopes?

Back

Their slopes are negative reciprocals of each other.

Front

What is the slope of a line parallel to a line with a slope of -5/6?

Front

What is the slope of a line parallel to a line with a slope of 3?

Back

3

Front

What does it mean for two lines to be neither parallel nor perpendicular?

Back

Their slopes are neither equal nor negative reciprocals.

Front

If a line has a slope of 2, what is the slope of a line that is perpendicular to it?

Back

-1/2

Front

What is the slope of a line that is perpendicular to a line with a slope of -4?

1/4

Front

In the equation of a line, what does 'b' represent in y=mx+b?

Back

Y-intercept

Front

If two lines have slopes of 1/3 and -3, are they perpendicular?

Back

Yes, because they are negative reciprocals.
