Answer :

Given:

Cost of each puppy = $200

Number of puppies = 8

Here, the equation for total cost of puppies will be:

C = 200x

Where x represents the number of puppies sold

Cost of 1 puppy = $200

Cost of 2 puppies = $200(2) = $400

Cost of 3 puppies = $200(3) = $600

If you continue with the pattern you'll see the graph has a rate of change of 200

To determine if the graph will be continuous or discrete, we have:

For a graph to be continuous, the points on the graph must be connected with a continuos line, while for a graph to be discrete the points are series of unconnected points just like in a scatter plot.

The graph of this will be a discrete graph. A discrete graph have set of values(points)

ANSWER:

B. discrete
