Top Chef--Ms. Phanchan wants to bake even more cookies to deliver to her students.
The graph shows the relationship between the cups of flour (f) she uses and the number of cookies (c) she can bake.
a) What equation can be used to represent the relationship between cups of flour used and the number of cookies baked? You must use the variables f and c.

Good work :) You can push ahead by..
1) Working on writing equations from graphs on IXL (Search code JKH)
2) If you have already mastered that, work on your lowest diagnostic skills!
