Front

What is the opposite reciprocal of a number?

Back

The opposite reciprocal of a number is obtained by flipping the fraction and changing its sign. For example, the opposite reciprocal of -1/10 is 10.

Front

What does the slope (m) represent in slope-intercept form?

Back

In slope-intercept form (y = mx + b), 'm' represents the slope of the line, which indicates the steepness and direction of the line.

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet or intersect. They have the same slope but different y-intercepts.

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees). The slopes of two perpendicular lines are negative reciprocals of each other.

Front

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

Back

The slope of the line is 2.

Front

How do you find the opposite reciprocal of a fraction?

Back

To find the opposite reciprocal of a fraction, flip the fraction and change its sign. For example, the opposite reciprocal of 1/2 is -2.

Front

What is the y-intercept in the equation y = 3x + 5?

Back

The y-intercept is the value of y when x = 0. In this case, the y-intercept is 5.

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 lines.

Front

What is the opposite reciprocal of 6?

Back

The opposite reciprocal of 6 is -1/6.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90 degrees).
