<strong>Instructions:</strong> Pick two points on the straight line in question and enter the X and Y values of each point. Note that the order of the points makes no difference.
</p>
<p>
Once you have entered both points, click the "Calculate Slope" button.

<p>
Mouse over the blue question marks for a further explanation of each entry field. More in-depth explanations can be found in the glossary of terms located beneath the Slope Calculator.
</p>
<p>
<strong>Important:</strong> Please double-check the results of this calculator yourself before considering them to be valid, as I can't test all possible number combinations. If you do find an issue with the calculator, please contact me and let me know what points you entered.
