"Yes, you there in the back!" You pointed to the girl raising her hand.
"I get the other stuff you explained, but what if the problem is on a graph?" She asked.
'A tough question, indeed' you thought, a grin slowly forming. "Great question, miss...?"
"Alice, sir."
"Yes, miss Alice," you continued. "Graphs are hard to understand, so for this demonstration we're going to use Abby's breast size, represented on a graph." Erasing the previous values on the chalk board, you then create a small grid. "Miss Abby, roughly how big are your breasts?"
"Well, after my growth I'd say it's about an E cup."
"Right, so 87 inches roughly" you wrote on the board, then drew a line in the graph. "This line, Alice, shows how big her bust is right now. The vertical we'll say is areola size, and the horizontal is the rest of the breast. If it is 87 on this graph, her areola will be roughly 4 inches wide. Go ahead and pick a number for me."
"3" she said. "Okay, so when we add 3 to the vertical-" he drew the line further right, 3 notches. "Abby, can you remove your shirt please?" She nodded, and took off her shirt, showing her nipples and areola expanding by 3 inches, making it look silver dollar sized. "As you can see, her areola expanded by 3 inches, as represented on the graph. Now, if we multiply by 3 on the horizontal we get?" You asked the class, a few raising their hands. "Yes, you sir?" You pointed to a skinny white boy in the middle.
"261, sir."
"Very good!" You said, drawing a horizontal line to the 261 mark. The result was ridiculous, Abby's bust expanding exponentially to the point of getting so big to touch the ground with little effort.
With that, the bell rang. Noticing you're out of time, you excuse yourself from the class and track down Melanie before exiting. "So, did you have a better time in there?" He asked his previous mode of transportation.
"Yeah, it sure changed it up today!" She still looked dejected, thinking about her next class. "That was fun, but Chemistry is going to suck for me today."
"Why's that?" You ask.
"My partner is sick today, and there's nobody left to partner up with!"
"Do you want me to come along for this one, too?" You smiled, earning a nod from her and a smug grin.
