RE-People with 100%, try this honors question:

Graph the solution for y -3 = -2(x + 3) +1

The equation simplifies to:Y = -2x-2

Unit 2: Linear FunctionsThis chapter will include some review from last year. Mostly, we will be solving equations – lots of equations!

SORT the graphs into 2 groups.

DISCRETE CONTINUOUS

DISCRETE CONTINUOUS

Based on how you sorted the graphs, how would YOU define DISCRETE & CONTINUOUS?

DisconnectedNot together

Dots

ConnectedTogether

“drivable”No holes
