BR Systems Students use symbolic, graphical, numeric and verbal representations of linear behavior to solve problems in population growth and equilibrium analysis. Students work extensively with linear models as they learn to create the line of best fit from a data set, find the point of intersection of two lines and interpret graphs. Lesson 1 Lake Victoria Students read and discuss the impending change to the ecosystem of Lake Victoria.
Students think about the predator-prey relationship qualitatively.
Lesson 2 Cost and Revenue Students solve systems of equations involving cost and revenue functions. Lesson 3 Linear Models Students develop skills in writing an equation of a line given two points and in finding the linear regression equation. This lesson explores how is the fisherman's profit is tied to changes in the fish population. Students graph data and find equilibrium points. The Business Model Students develop more fully the cost, revenue and profit equations.
