# Math Proficiency Placement Exam

The following is a list of competencies addressed on the exam.

The student will be able to:

1. Simplify real number expressions using order of operations.
2. Graph points and intervals of points on the real number line.
3. Classify real numbers as rational, irrational, integer, and/or non-integer values.
4. Identify real number properties such as commutativity, associativity, distributive law, identities, and inverses.
5. Translate verbal expressions into algebraic expressions.
6. Simpify algebraic expressions by combining like terms.
7. Evaluate algebraic expressions.
8. Solve linear equations.
9. Construct and use a linear model to solve an application problem.
10. Plot points in the Cartesian plane.
11. Graph a straight line.
12. Determine the x and y-intercepts of a line.
13. Determine the slope of a line.
14. Determine if lines are parallel or perpendicular using slope.
15. Use the point-slope formula to find the equation of a line.
16. Use the slope-intercept form of a line to determine its slope and y-intercept.
17. Determine whether an expression represents a function using various techniques, including the Vertical Line Test.
18. Evaluate functions.
19. Find the sum, difference, product, and quotient of functions.
20. Form the composition of functions.
