Question

the cost y (in dollars) for x pounds of deli meat is represented by the equation y=3.5x, graph the equation

Answer 1

I don't have the graph, but I'll explain what you need to do. Plot a point with the coordinates (1,3.5), (2,7), (3,10.5), and (4,14). Now draw a straight line connecting al these pints but don't go past the origin into the negative as in this situation it is not possible. There! Now you have a graph :)
