Given the equation for dosage as:
and dosage for an adult as 200 mg
Now, in order to find the slop of the equation , the dosage of an adult is 200 is substituted in the equation of dosage.
The equation will look like -
Now, the equation has reached the form of equation - , where a = slope of the equation and b is the intercept.
In the equation, , slope is 8.34 and it represents the change in mg for every 1 year change.
