Today, we looked at functions that have two variables (namely x and y) and learned how to solve them. First, we reviewed how to make a data table (x-y function chart), and select x values to evaluate. Every x value will generate a particular y value, and the answers are expressed as ordered pairs where the x value is listed first and the y value is listed second. Students learned how to write an equation in function form.
