Question

What is the difference between a linear solid line and a set of unconnected points? I don't understand. (Giving 15 points!)

Answer 1

Linear line is constant & the Non - linear ( unconnected dots ) are not constant which means the rate is constantly changing

Answer 2

A connected, solid, graph is called a continuous graph. A disconnected graph, made of separate dots, is called a discrete graph.

Explanation:

A discrete graph shows us that there are no data values between the whole numbers on which the points are plotted. This generally means no decimal portions. However, when representing time, we can have a decimal portion of a year; this means the graph would have values between the whole numbers and would be continuous, or solid.
