I’m confused because I don’t know what I would put for “What scale factor takes the original polygon to its smaller copy”.

Which of the following could be the graph of the equation y = -2x + 5

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.

The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left
