Estimate the number of cells in a 75 kilogram person assuming the human body is 100% water and 1 liter of water weighs 1 kilogram.

positive

step-by-step explanation:

the quadrant is facing upwards

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
