I NEED HELP WHATS 1+1

Find the slope of the line y =8/9x + 1.

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.

What is the equation of a line passing through the point (6,1) and parallel to the line whose equation 3x=2y+4
