Determine slope and intercept from an equation
Objective: SWBAT determine the slope and y-intercept from any linear equation.
Big Idea: Y has been a very, very bad boy. :) Isolate him so that we can figure out the slope and intercept.

Warm-up
Each day, students complete a Warmup that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.
For a video narrative about how I structure each lesson, and how the warm-up fits in, click here.
I really like the warm-up problems today, because they push kids to apply their understanding to unfamiliar problems - in this case, focusing on matching the equivalent graphs and equations... I like to ask: "Which answer choice is wrong, and why?" Kids then use reasoning about the positive or negative nature of the slope, as well as where the line crosses the y-axis, which enriches their understanding of multiple representations of linear functions.
