Step 3. Use the equation of the calibration curve to adjust measurements taken on samples with unknown values. Substitute the measured value as x into the equation and solve for y (the true value). In the example from step 2, y = 1.05x + 0.2. Thus, a measured value of 75.0, for example, would adjust to y = 1.05(75) + 0.2 = 78.9.
1. Convert the equations into y= form In order to graph an equation on your calculator, the left side of the equation must only contain y. This is pretty easy to do, especially if you are dealing with linear equations.
