Question

Sami consulted a dietitian regarding weight loss and was given a nutrition plan to follow. The dietitian informed Sami, if she follows the plan, her results should be in alignment with the following linear model. In this model, x represents the number of weeks on the plan, and y represents Sami's weight (in pounds). Interpret the y-intercept

Answer 1

\[y=342-2.2x\]

Answer 2

@Michele_Laino this is the equation it gave me

Answer 3

A.The y-intercept represents Sami's goal weight upon completion of the plan.

B.The y-intercept represents Sami's weight upon starting the plan.

C.The y-intercept represents the amount of weight Sami should lose in total

D.The y-intercept represents the amount of weight Sami should lose each week

Answer 4

i guess what im asking is will u walk me through how to slove the equation

Answer 5

the y-intercept, is the weight y at x=0, so we have:
y-intercept = 342-2.2*0= 342

Namely the y-intercept is the weight at the starting of the plan

Answer 6

thats awsome but i dont understand

Answer 7

since the quantity x measures the number of weeks of the plan, then we have that at x=0, namely at the week number zero, the weight is:
y=342- 2.2* 0= 342-0= 342

Answer 8

ok

Answer 9

:)

Answer 10

so that doesnt help me to solve the equation

Answer 11

ugh i hate math and i suck at it to
