Math Expressions Graphs

A bar graph shows the number of books read by students in a month. If the bar for 5 books is twice as high as the bar for 3 books, how many students read 5 books if 6 students read 3 books?

• 12

• 10

• 8

• 15

Create a bar graph: If you have data showing 5 apples, 3 bananas, and 7 oranges, which fruit should have the tallest bar?

• Apples

• Bananas

• Oranges

• All are equal

Match the sub-category with its description. Solve, graph, and model multiple types of expressions. Interpret and use many different kinds of equations, such as linear, polynomial, radical, and exponential relationships. Find solutions to systems of equations, even when represented by a simple matrix equation, and apply results to real-world contexts.

• Functions

• Algebra

• Number & Quantity

Match the sub-category with its description. Demonstrate knowledge of function: definition, notation, representation, and application. Use functions including linear, radical, piecewise, polynomial, exponential, and logarithmic. Manipulate and translate functions, as well as interpret and use important features of graphs.

What is the Origin in a coordinate plane?

• The point (0,0) in a coordinate plane where the horizontal axis intersects the vertical axis.

• A point where a graph crosses the x-axis.

• A point where a graph crosses the y-axis.

• A graph of distinct points.

Answer explanation

The Origin is defined as the point (0,0) in a coordinate plane, where the horizontal x-axis intersects the vertical y-axis. This is the correct choice, as it specifically identifies the location of the Origin.

What is the Order of Operations?

• The order in which operations in an expression are evaluated using PEMDAS.

• The order in which numbers are added.

• The order in which equations are solved.

• The order in which graphs are drawn.

Answer explanation

The correct choice explains that the Order of Operations refers to the sequence of evaluating expressions using PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), which is essential for accurate calculations.

What is a Continuous Graph?

• A graph made up of all possible points connected in lines or curves.

• A graph of distinct points.

• A math phrase with no equal sign.

• A number that is raised to a power.

Answer explanation

A Continuous Graph is defined as a graph made up of all possible points connected in lines or curves, illustrating a smooth transition between points. This distinguishes it from graphs of distinct points.

Which graph is proportional, and why?

• Graph 1 because it is straight

• Both graphs are proportional

• Graph 2 because it is steep

• Graph 2 because it is straight, and goes through the origin
