Question

(a) find the slope of the graph of c. what does it represent? we are given d = 300. substitute 300 for d in the equation c = 0.0417d(a + 1). after simplifying, we get c = (12.51)a + 12.51. step 2 when a linear function is written in the form y = mx + b, the slope is given by m. since c = 12.51a + 12.51 is a linear equation in this form, the slope of the graph of c is. the slope represents the ---select--- of the dosage for a child for each change of 1 year in age. submit skip (you cannot come back)

Explanation:

Step1: Substitute D=300 into formula

$c = 0.0417(300)(a + 1)$

Step2: Calculate coefficient of (a+1)

$0.0417 \times 300 = 12.51$

Step3: Rewrite as linear function

$c = 12.51a + 12.51$

Step4: Identify slope from y=mx+b

Slope $m = 12.51$

Answer:

The slope of the graph of $c$ is $12.51$. It represents the increase of the dosage for a child for each change of 1 year in age.
