Cowling's Rule is a method for calculating pediatric drug dosages. If a denotes the adult dosage (in milligrams) and if t is the child's age (in years), then the child's dosage is given by

D(t) = (t + 1/24)a

(a) Show that D is a linear function of t.

Hint: Think of D(t) as having the form

D(t) = mt + b.

What are the slope m and the y-intercept b?

m = ______

b = ______
