Parallel and Perpendicular Slopes

Front

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

Back

The slope of a line that is perpendicular to a line with slope m is -1/m. Therefore, the slope is 1/4.

Front

What does 'm' represent in the equation y=mx+b?

Back

'm' represents the slope of the line.

Front

If two lines have the same slope, what can we say about them?

Back

They are parallel.

Front

What is the y-intercept in the equation y=mx+b?

Back

The y-intercept is the value of y when x=0, represented by 'b'.

Front

Write the equation of a line that is parallel to y = 3x + 2 and passes through the point (1, 5).

Back

y = 3x + 2.

Front

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

Back

The product of their slopes is -1.

Front

Identify the slope of the line represented by the equation y = -2x + 3.

Back

The slope is -2.

Front

Which of the following lines are parallel: y = 2x + 1 and y = 2x - 4?

Back

They are parallel because they have the same slope of 2.

Front

If a line has a slope of 0, what type of line is it?

Back

It is a horizontal line.

Front

What is the slope of a line that is perpendicular to a line with a slope of 5?

Back

The slope is -1/5.
