Hans looks up the latitude and average January temperature (in degrees Celsius) of a variety of cities in the northern hemisphere. He then creates a scatter plot showing each city’s latitude on the x-axis and temperature on the y-axis. Do you think this graph will have a positive, a negative, or no trend? Explain.

Would you expect the trend line have a positive or negative slope?

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?
