Vaati pov.

"Want to go through your lesson a bit early?" Vio comes in asking me. Majora is in his room and won't be getting a lesson today as he's running a fever. 

"Sure, just let me get my stuff out," I woke up early to watch the thunderstorm this morning. 

"I'll get the table set up for us, I'll even put on some tea for us both," I look at him, he always offers to make tea.

Getting to the table I hear the kettle bowling away. I get out my mathematics as that's what Vio always starts with. "What kind of tea do you want me to put into your cup?" He calls from the kitchen.

"I'll take some green tea," I call back to him. I sharpen my pencil a little as he puts the tea bags in and comes over.

"We're going to start with graphing, what do you think a transformation is?" He asks placing his hand on my paper and keeps it there. He does that to keep me from writing on it when he doesn't want me writing something. 

"Wouldn't it be any change to what is considered the original graph," I ask looking at my calculator. 

"That's close but not right, it's a specific kind of change, I'll go get the tea,"

He gets up and pours the hot water, puts two spoons of sugar into mine. Something is up. He always asks me how I want my tea, even if it's always the same. Two sugar, either regular old milk or canned evaporated milk. Depending on how I want it to taste that day. "I'll take evaporated," I call out still having my eyes on him.

He comes back. "A transformation is when the graph is moved. Either vertically or horizontally. This is the easiest part," he stirs his tea as I write that down. "Here's the basic formula of it," he takes my paper writing it down. I take it back and look at it. Mapping notation: x + k, y + h. Formula [x - k] + h. If h > 0 the graph moves up, if h < 0 the graph moves down. If k > 0 move left, if k < 0 move right.
