Using a graphing utility, we can plot the given complex number in the complex plane as shown below:

![complex number graph](https://www1.webassign.net/images/objects/qc/topic24405/24405-ex10-08-alt.gif)

From the graph, we see that the real part is negative and the imaginary part is positive. Therefore, the complex number is of the form a + bi where a is negative and b is positive. The closest answer choice to this form is C, which represents -1.7976 + 0.8767i.
