AIM: How can you compare the costs represented by two linear relationships?
HW: Enjoy your evening
Do Now: Determine whether the relationship in the table is linear or not. Explain. If it is linear find the equation.
x | -1 2 6 9 20
y | -7 2 14 23 56
Classwork: We looked at tables to determine if relationships are linear. With the tables, we were able to find constant rates of change (if they existed) and then used those to find y-intercepts. With both of those pieces, students were able to write equations to linear relationships.
