That week we learned how to interpret graphs of functions and to do distance formula.
interpretting graphs is explaining what is happening in the graph by how and what the slope looks like. When it is a flat line it is a constant rate, if it is going up your increasing and going down is decreasing.
When I was walking home, I walked at a constant rate, then slowed down and and walked at that rate, then started walking again at a faster rate for a short while then walked at a constant rate till I slowed down to stopped at my doorstep.
this is how you interpret a graph function and how to do it.
