HONORS: Slopes: Parallel, Perpendicular & write equations

Front

What is the slope of a horizontal line?

Back

Zero

Front

What type of slope do vertical lines have?

Back

Undefined

Front

What is the relationship between the slopes of perpendicular lines?

Back

They have opposite signs and are reciprocals of each other.

Front

What is the slope of parallel lines?

Back

The same

Front

If a line has a positive slope, what does that indicate about its direction?

Back

The line rises from left to right.

Front

If a line has a negative slope, what does that indicate about its direction?

Back

The line falls from left to right.

Front

What is the slope of the line represented by the equation y = 3x + 2?

Back

3

Front

What is the slope of the line represented by the equation y = -2x + 5?

Back

-2

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What does it mean if two lines are parallel?

Back

They have the same slope and will never intersect.
