What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is less than, greater than, less than or equal to, or greater than or equal to the other.

What is the solution set for the inequality -4x + 8 ≤ -x - 7?

Back

{ x | x ≥ 5 }

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

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 are opposite reciprocals?

Back

Opposite reciprocals are two numbers whose product is -1. For example, if one slope is m, the opposite reciprocal is -1/m.

Front

How are the slopes of perpendicular lines related?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

How are the slopes of parallel lines related?

Back

The slopes of parallel lines are the same.
