Using similar triangle method to find the height of the house if its shadow is 31.25 feet. A nearby tree is 32 feet tall and casts a 40 foot shadow at the same time of day.

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.

Math it's appreciated. (picture provided)
