3-1 Relations and Functions – We learned that a relation is an association between sets of ordered pairs where the domain consists of the set of x-values and the range consists of the set of y-values. Then we learned to identify functions and their components in a variety of forms such as graphs, tables, and ordered pairs. Next we learned that a relation is a function only if each element of the domain is assigned to exactly one element in the range. Finally we identified constraints on the domain based on real-world problems.
We went over problems that Sam did not understand on the practice test that he was assigned for homework.

Review for test on Topic 2 Linear Equations. We practiced how to write an equation in point-slope form from a graph. Then we practiced writing the equation from two points on the line. Next we practiced how to use the standard form to plot a graph, find the slope, and x, y-intercepts. We reviewed the steps to write and graph linear equations in standard form. We practiced changing from standard form to slope-intercept form.
