Alright what’s the slope of THISSS line

If lmn=xyz, which congruences are true by cpctc? check all that apply

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.

Can someone me do math because i am having a breakdown rn because i don’t get it
