Answer:
Per hour decay of the isotope is 0.96%.
Step-by-step explanation:
Amount of radioactive element remaining after t hours is represented by

where a = initial amount
t = duration of decay (in hours)
Amount remaining after 1 hour will be,

y = 0.9904a
So amount of decay in one hour = a - 0.9904a
= 0.0096a gms
Percentage decay every hour = 
= 
= 0.958 %
≈ 0.96 %
Therefore, per hour decay of the radioactive isotope is 0.96%.
Answer:
y - b = -4(x - a)
Step-by-step explanation:
If the line passes through (a, b), then the point-slope form of the equation of the line is y - b = -4(x - a). Where's the line you mention?
