Diana is a piano teacher who charges $45 per hour plus an additional flat fee of $20 for travel. the equation that represents this situation is y = 45x + 20, where x represents the number of lesson hours, and y represents the total cost. another piano teacher, paula, creates a graph to compare the total amount diana charges with the total amount she charges for lessons. paula observes that the graph of her function looks the same as the graph of diana's function except that it is shifted 2 units below it. select the function that represents the total amount paula charges. a. f(x) = 43x + 20 b. f(x) = 45x + 18 c. f(x) = 43x + 18 d. f(x) = 45x + 22

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.
