The image is a line graph that shows the percentage of seats in Washington State Legislature held by women in the United States from 2005 to 2015. The x-axis represents the years, starting from 2005 and ending in 2015, with the y-axis representing the percentage.

There are two lines in the graph, one in purple and one in black, that represent the number of seats held in each seat. The purple line represents the percentage, while the black line represents a percentage of the seats held. The line in purple represents the total number of women held, ranging from 0 to 100%.

The graph is displayed on a white board with a black stand, and there is a window in the background with a view of a city skyline. The text on the board reads "Figure 10: Percentage of Seats in Washington Legislature Held by Women".
