Manipulating formulas

The  exercise appears under the Algebra I Math Mission. This exercise practices rewriting formulas in terms of one of the "lesser" on non-standard variables.

Types of Problems
There are twp types of problems in this exercise:


 * 1) Isolate the specified variable: This problem provides a formula with several different variables. The student is asked to solve for one of the variables and type the answer in the space provided.Manfor1.png
 * 2) Rewrite the equation and find the intercept: This problem provides a function y in terms of x. The student is asked to solve for x in terms of y and use this form to find the x-intercept of the equation.Manfor2.png

Strategies
Knowledge of the process for solving general linear equations would assist with accuracy and efficiency on this exercise.
 * 1) The x and y intercepts are transposed via inversion (solving for x in terms of y).
 * 2) Once the equation is rewritten in the second type of problem, plug in y=0.

Real-life Applications

 * 1) Linear equations, as the initial stage of polynomials, have many applications in several fields of study.
