9. Study Question 4: Graph an equation in standard form. Graph 5x-3y=6

10. Modeling real world data If a quantity changes at a constant rate over time, it can be modeled by a linear equation. The y-intercept represents a starting point, and the slope represents the rate of change.

11. Study Question 5: Write an equation in slope-intercept form The natural sweeteners used in foods include sugar, corn sweeteners, syrup, and honey. Use the information about natural sweeteners. a.The amount of natural sweeteners consumed has increased by an average of 2.6 pounds per year. In 1989 each person consumed an average of 133 pounds of sweeteners Write a linear equation to find the average consumption of natural sweeteners in any year after 1989. b.Graph the equation c.Find the number of pounds of sweeteners consumed in 2009.
