In order to find the corresponding graph, let's find two points that are on the line.
To do so, let's choose values of x and then calculate the corresponding values of y:
So we have the points (0, 4) and (8, 0).
Looking at the options, the graph that has these points is the fourth graph.
In a geometric sequence, consecutive terms have a common ratio:
This means that, in order to build a gometric sequence, we must choose an initial value and a common ratio
, and we'll multiply each term by
to get the next one:
This implies that
And so in this case we have
