Answer

Explanation:

Step1: Analyze the initial - length and daily - cut

The initial length of the bread is 65 cm and 15 cm is cut each day. So the remaining length $l$ after $d$ days is the initial length minus the total length cut in $d$ days. The total length cut in $d$ days is $15d$ (since 15 cm is cut per day). So the equation is $l = 65-15d$.

Step2: Determine the type of the graph

The variable $d$ represents the number of days, which can only take on non - negative integer values ($d = 0,1,2,\cdots$). Since the independent variable $d$ has a set of distinct, separate values, the graph of the equation is discrete.

Answer:

A. $l = 65 - 15d$; discrete
