What is the answer for this question

Solve - pv + 40 < 65 for v solve 7w - 3r = 15 for r

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.

Are the corresponding angles congruent? explain why or why not.
