2. A new experimental diet for hens determines that the average weight (grams) of a hen can increase in a linear fashion over a period of 50 days. The average mass of a hen starting the diet is 150 grams. After 30 days the average mass is 690 grams. Draw a graph and give the equation for this situation.
