Essential Algebra 1 Vocabulary

What is a coefficient in algebra?

• A coefficient is the number in front of a variable.

• A coefficient is the sum of all variables in an equation.

• A coefficient is a type of algebraic expression.

• A coefficient is the product of two variables.

What is the difference between an equation and an inequality?

• An equation states that two expressions are equal, while an inequality shows that one expression is greater than, less than, or not equal to another.

• An equation shows that one expression is greater than another, while an inequality states that two expressions are equal.

• An equation is a mathematical statement that includes variables, while an inequality does not.

• An equation can only contain numbers, while an inequality can contain both numbers and variables.

What inequality is represented by the phrase 'no more than'?

• >

• ≥

• ≤

• <

What is the slope of perpendicular lines?

• The slopes of perpendicular lines are equal.

• The slopes of perpendicular lines are opposite reciprocals.

• The slopes of perpendicular lines are the same sign.

• The slopes of perpendicular lines are always positive.

What is the x-intercept of a line?

• The point where the line crosses the y-axis.

• The point where the line crosses the x-axis.

• The slope of the line at the origin.

• The distance from the origin to the line.

What is the slope-intercept form of a linear equation?

• y = mx + b, where m is the slope and b is the y-intercept

• y = ax^2 + bx + c, a quadratic equation

• y = mx + c, where m is the slope and c is the y-intercept

• y = b/x + m, an inverse relationship

What does it mean for two lines to be parallel?

• They intersect at a right angle.

• They have different slopes and meet at some point.

• They have the same slope and never intersect.

• They are always horizontal.

What does it mean for two lines to be perpendicular?

• Two lines are parallel if the product of their slopes is 1.

• Two lines are perpendicular if the product of their slopes is -1.

• Two lines intersect at a right angle if their slopes are equal.

• Two lines are perpendicular if they have the same slope.

What is the slope of parallel lines?

• The slopes of parallel lines are the same.

• The slopes of parallel lines are different.

• The slope of parallel lines is zero.

• The slope of parallel lines is undefined.

What is a linear inequality?

• A linear inequality is an equation that represents a straight line.

• A linear inequality is an inequality that involves a linear function, such as y < mx + b.

• A linear inequality is a type of polynomial equation.

• A linear inequality is a function that has no variables.
