Given:
Initial mass, m₀ = 23 g
Decay constant, k = 0.13
Exponential decay obeys the equation

where t = time, days
For half life, the mass is m = m₀/2.
Therefore

Answer: The half life is 5.33 days
Slope is 4/5
The equation is Y = mx + b
M represent the slope
In your equation, 4/5 is the slope.
The opposite of 4 is negative 4, or -4
