Which of the following describes how circulatory and respiratory systems work together to help maintain homeostasis?

By delivering oxygen to the cells

Step-by-step explanation:

This is the answer because:

The respiratory system is responsible for moving gases into and out of the blood because it gives the bloodstream the oxygen needs. The circulatory system is responsible for moving blood to all parts of the body and transport nutrients. The circulatory system works with the respiratory system to exchange carbon dioxide and oxygen.

step-by-step explanation:

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
