The fastest recorded Hawaiian lava flow moved at an average speed of 6 miles per hour. The function y= 6x describes the distance y the lava moved on average x hours. Graph the function. Use the graph to estimate how many miles the lava moved after 4.5 miles.

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?
