PLEASE HELP ASAP! the function (below) represents he velocity of air flow of normal breathing cycles, where x is measured in seconds. A cycle consists of inhaling, where air flow is positive, and exhaling where air flow is negative. The air flow is measured in liters per second. how long is one complete cycle and what will the air flow be in 150 seconds?

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
