Remember!
1. x, y are interchangeable in these equations.
2. ∆x and ∆y are calculated as either x - xo or y - yo

Equations
Equations 1,3,4 can all be used because they contain the target variable, (a) and all other variables
are known. Equation 2 could not be used because it does not have (a). Equation 1 would be the
easiest to use because it is the easiest in terms of the amount of algebra needed to rearrange the
equation.
