Answer:

y = -x+6

Step-by-step explanation:

We can use the slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = -1x+b

Substitute the point into the equation

-8 = -1*2 +b

-8 = -2+b

-8+2 = -2+b+2

-6 =b

y = -x+6

adelina 88 [10]

Answer:

$L = 10(\frac{1}{2} )^{t-4}$

Step-by-step explanation:

If t is the number of days since Sofia took the medication of 10 mg, then the amount of medication in her system after t days will be $S = 10(\frac{1}{2} )^{t}$ .

So, the concentration of medicine in blood decreases by a factor of one half every day.

If we count the number of days from today and Lexi takes 10 mg of the same medicine four days later then the amount of medicine left on her body after t days will be $L = 10(\frac{1}{2} )^{t-4}$ . (Answer)
