Answer:
Step-by-step explanation:
<em>1).</em>
(a). Yes, the graph is linear.
(b). Rate of change is a slope m, m = (60 - 80) / (10 - 0) = - 2
<em>2).</em> Graph is not proportional, because y-intercept is (0, 80) and not (0, 0)

Step-by-step explanation:
im sorry if this is wrong!
Consider a function f(x), the linear approximation L(x) of f(x) is given by

Given the quantity:

We approximate the quantity using the function

, where x = 203.
We choose a = 200, thus the linear approximation is given as follows:
This is the correct graph.
Find the intercepts, if there are any. ...
Find the vertical asymptotes by setting the denominator equal to zero and solving.
Find the horizontal asymptote, if it exists, using the fact above.
The vertical asymptotes will divide the number line into regions. ...
