What is the y-intercept?

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

• The point where the line crosses the y-axis, represented by the value of y when x = 0.

• The slope of the line at the origin.

• The value of x when y = 0.

What is a system of equations?

• A single equation with one variable.

• A set of two or more equations with the same variables that are solved together.

• An equation that has no solution.

• A method to solve quadratic equations.

What is a linear equation?

• An equation that makes a straight line when graphed, typically in the form y = mx + b.

• An equation that represents a curve on a graph.

• An equation that has no solutions.

• An equation that can only be solved using calculus.

What is a variable in algebra?

• A symbol, often a letter, that represents one or more numbers.

• A fixed value that does not change.

• A mathematical operation such as addition or subtraction.

• A type of equation that has no solution.

What is a function?

• A relation where each input (x-value) has exactly one output (y-value).

• A set of ordered pairs where no two pairs have the same first element.

• A mathematical operation that combines two or more numbers.

• A graphical representation of data points.

What does it mean to graph an inequality?

• To represent the solutions of the inequality on a number line or coordinate plane, often using shading.

• To find the exact value of the variable in the inequality.

• To create a table of values that satisfy the inequality.

• To convert the inequality into an equation and solve for the variable.

What is the distributive property?

• A property that states a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside a set of parentheses.

• A rule that states that the sum of two numbers is equal to the product of those numbers.

• A principle that allows you to divide a number by the sum of two other numbers.

• A theorem that states that the product of two numbers is always greater than either of the numbers.

What is the difference between independent and dependent variables?

• The independent variable is the output (y), while the dependent variable is the input (x).

• The independent variable is the input (x), while the dependent variable is the output (y) that depends on the input.

• Both independent and dependent variables are the same and can be interchanged.

• The independent variable is a constant, while the dependent variable varies.

What is the purpose of solving an equation?

• To find the value(s) of the variable(s) that make the equation true.

• To simplify the equation to its lowest terms.

• To graph the equation on a coordinate plane.

• To determine the number of solutions the equation has.

What are like terms?

• Terms that have the same variable raised to the same power.

• Terms that have different variables.

• Terms that are constants.

• Terms that have the same coefficient.
