Excel SLOPE Function and Scatter Plot for a Pricing Formula

This video takes us back to my very first paid project in Excel. A photographer had a problem calculating the price of a finished and framed photo. The main part of the problem was the mystery around the price of the frame.

We gathered receipts and I figured, “what the heck, let’s plot the known data on a grid.”
The Excel scatter plot showed a straight line. That made it easy to figure out the frame shop’s pricing formula.

The equation of a straight line: y=mx+b

 
y = final price
m = slope * length * width + b
EASY!!!
