Parallel and Perpendicular Slopes

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

'b' represents the y-intercept, which is the point where the line crosses the y-axis.

Front

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

Back

'm' represents the slope of the line, indicating its steepness and direction.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope (m) but different y-intercepts (b).

Front

How do you determine if two lines are perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1 (m1 * m2 = -1).

Front

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

Back

The slope of the line y = -2x + 5 is -2.

Front

What is the y-intercept of the line y = 3x + 2?

Back

The y-intercept of the line y = 3x + 2 is 2.

Front

Which equation is perpendicular to y = -6x + 2?

Back

The equation y = 1/6x + 4 is perpendicular to y = -6x + 2.

Front

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

Back

If two lines have the same slope, they are parallel.

Front

What is the slope of a line that is horizontal?

Back

The slope of a horizontal line is 0.
