Example Question #1 : Rearrange Formulas And Solve Equations: Ccss.Math.Content.Hsa Ced.A.4

To calculate the slope of a line, the following formula is used.

Solve this equation for .

Possible Answers:

Correct answer:

Explanation:

This question is asking to rearrange the slope formula to highlight a quantity of interest, specifically 

To rearrange the formula, perform algebraic operations. Recall that whatever operation that is done to one side needs to also be done on the other side in order to keep the equation balanced. 

First, multiply both sides by the quantity  in order to move it from the right side of the equation to the left side. Performing the opposite operation allows for rearranging to occur. 

Next, add  to both sides of the equation.

Therefore, the equation solved for  is
