Any help is greatly appreciated!

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.

Which expression will have the same sum as 3_8 + 1/4?

When 142 is added to a number the result is 64 more times the number my options are 35 37 39 41
