1. ernest calculated the slope of the graph during the uphill climb to be 10 . determine whether his calculation was correct or incorrect and explain why . 2. confirm or disprove ernest's work by selecting two different points and applying the slope formula. 3. what does the slope tell you about the rate of change in elevation during ryan’s uphill climb? what was the total elevation change?

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
