a. You earn $11 per hour, and so if you work 18 hours, you multiply "11 x 18" to find out how much money you would make during that time period.
b. To find out how many hours you are required to work to be paid $275, you simply need to divide by 11, seeing as how that is how much you would be paid per hour. So, the equation would look like this: "275/11 = 25"
Yes algebra!!! Anyways, the m of y=mx+b is the slope of the graph, this affects the graph by making the line go in a angle either negatively or positivly B is where the plot lies on the y line (up and down)
