One Step Equation Vocabulary review

What is an equation?

• A mathematical statement that asserts the equality of two expressions, typically containing an equal sign (e.g., x - 5 = 2).

• A formula used to calculate the area of a circle.

• A type of graph that represents data points in a coordinate system.

• A method for solving inequalities.

What is the difference between an expression and an equation?

• An expression has an equal sign and represents a value, while an equation does not.

• An expression does not have an equal sign and represents a value, while an equation states that two expressions are equal.

• An expression is a type of equation that includes variables, while an equation is a fixed statement.

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

What does it mean to isolate a variable?

• To combine like terms in an equation.

• To manipulate an equation so that the variable is on one side and all other terms are on the other side.

• To eliminate the variable from the equation entirely.

• To substitute the variable with a constant value.

What is a term in an expression?

• A term is a single mathematical component of an expression, which can be a number, a variable, or a product of numbers and variables.

• A term is the sum of two or more expressions.

• A term is a type of equation that includes variables and constants.

• A term is a mathematical operation that combines numbers and variables.

What is a linear equation?

• An equation of the first degree with no exponents greater than one, which graphs as a straight line.

• An equation that can have exponents greater than one, resulting in a curve.

• An equation that represents a relationship between two variables in a non-linear fashion.

• An equation that only contains constants and no variables.

What is a variable in an equation?

• A variable is a constant value that does not change.

• A variable is a symbol (usually a letter) that represents an unknown value in an equation (e.g., n in -2n = -7).

• A variable is a number that is always positive.

• A variable is a term that represents a fixed quantity.

What is a constant in mathematics?

• A variable that can change value

• A fixed value that does not change (e.g., in the expression 3x + 5, 5 is the constant)

• A mathematical operation that varies

• A type of equation that has no solution

What does it mean for an expression to be simplified?

• To make the expression longer and more complex.

• To combine like terms and reduce it to its simplest form.

• To change the expression into a different variable.

• To eliminate all variables from the expression.

How many terms are in the expression -2 + 4y?

• 1 term

• 2 terms

• 3 terms

• 4 terms

What is the purpose of solving an equation?

• To find the value of the variable that makes the equation true.

• To simplify the equation to its lowest terms.

• To determine the number of solutions an equation can have.

• To graph the equation on a coordinate plane.
