Mercedes created color panels for a wall using a mix of only green and yellow paints. She plotted the quantities of green and yellow paints used for each mix and connected them using a line segment, as shown in the graph. A line graph titled Color Mix, with Quantity of Yellow Paint, in millimeters, on the X axis and Quantity of Green Paint, in millimeters, on the Y axis. The X axis has a scale from 0 to 10 with an increment of 1. The Y axis has a scale of 0 to 20 in increments of 2. A straight line connecting 2, 2 and 10, 18 is drawn. Which statement best describes the domain of the function represented in the graph? 2 ≤ x ≤ 10 2 ≤ x ≤ 18 10 ≤ x ≤ 18 0 ≤ x ≤ 10
