Answer: y-7 = 4(x+3), choice B
============================================
Point slope form is generally
y-y1 = m(x-x1)
we have m as the slope and (x1,y1) as the point this line goes through. In this case,
m = 4
(x1,y1) = (-3,7) so x1 = -3 and y1 = 7
So,
y-y1 = m(x-x1)
y - 7 = 4(x - (-3))
y - 7 = 4(x + 3)
which is why choice B is the answer

Answer:
The half life of the radioactive substance is 277 hours.
Step-by-step explanation:
initial mass, No = 100 mg
mass decayed = 2% = 2 mg
Mass remained , N = 98 mg
time, t = 8 hours
Let the half life is T.
Use the equation of radioactivity
