Question

Maxine is buying extra pages for her photo album. Each page holds exactly 8 photos. Sketch a graph to show the maximum number of photos she can add to her album if she buys 1, 2, 3, or 4 extra pages. Tell whether the graph is continuous or discrete. Please tell why it is continuous or discrete and how you got your answer.

Answer 1

Ok so I can't sketch a graph for you because I don't know how to but i can give a formula that will help you graph it on your own. The equation is y = 8x having x represent the amount of extra pages you want to add. I came to this equation because if 8 photos can fit in each extra page and x represents the the extra pages then 8 photos is the slope for the equation y = mx + b. So if you were to graph this you will get a continuous line because it has no holes.
