If a planar drawing of a graph has 15 edges and 8 vertices, how many faces does the graph have?

To determine

The number of faces does a graph have whose edges and vertices are 15 and 8.

**Given information:**

Number of vertices = 8

Number of edges = 15

**Formula used:**

__Euler's Formula: __v + f = c + 2, where f is the number of faces, v is the number of vertex and c is the number of edges.

**Calculation:**

Number of vertices = 8

Number of edges = 15
