In this inquiry lesson, students discover basic information about y = mx + b. The context of temperature allows for realistic meaning for positive and negative values for both the slope and the y-intercept. Students work with tables, graph and equations as they find how temperature changes over time.
This resource includes a 5 page packet for students, as well as three practice pages that could be used as in class practice or homework. There is also a notes/graphic organizer about slope-intercept form. I use this packet to introduce the ideas of slope and y-intercept before formally introducing the slope formula and slope-intercept form. As we continue working with slope-intercept form, this is a convenient context to refer back to.
