The equation of some line in Standard form is 2x + By = 9. In order to graph this line, you need to know the value of B. Fortunately, you do know that the ordered pair (-3,5) is a solution to the equation. What is the value of B? Then, graph the line. A NYC street vendor spends $75 a day on supplies (napkins, mustard packets, etc.). It costs the vendor $0.50 to make a pretzel. (a) What quantity would x represent? What quantity would y represent? (b) Write an equation to represent the vendor's daily costs.
