Keira created color panels for a wall using a mix of only red and blue paints. She plotted the quantities of red and blue paints
used for each mix and connected them using a line segment, as shown in the graph below: A line graph titled Color Mix, with Quantity of Blue Paint, in millimeters, on the X axis and Quantity of Red Paint, in millimeters, on the Y axis. The X axis has a scale from 0 to 9 with an increment of 1. The Y axis has a scale of 0 to 18 in increments of 2. A straight line connecting 3, 2 and 7, 12 is drawn. Which statement best describes the domain of the function represented in the graph? (1 point)
3 ≤ x ≤ 12 or x is between 3 and 12, inclusive 3 ≤ x ≤ 7 or x is between 3 and 7, inclusive 2 ≤ x ≤ 12 or x is between 2 and 12, inclusive 2 ≤ x ≤ 7 or x is between 2 and 7, inclusive </span> The answer is the 3rd option
The answer is 11 becauze the pattern works like this - 18÷2=9 20÷2=10 22÷2=11 Basically the X axis being divided by 2 which equals the Y axis (eg: X÷2=Y
