This week in math, we will be finishing up our lesson on scale factor - the multiplicative factor that is used to produce enlargements (scale factor greater than 1.0) and reductions (scale factor less than 1.0). Identifying and applying the scale factor is often an easier (and quicker) way to solve proportions than the traditional cross-multiplication method. We will finish the week with a quick lesson and quiz on graphing proportional relationships. For a relationship to be proportional on a coordinate plane, it must:
1) Be a straight line
2) Pass through the origin (0,0)
