The gradient of the graph is -1/3 and the y-intercept of the graph is 1
The equation of the line is y = -x/3 + 1
The shaded area represents y values less than or equal to the y values represented by the line.
This gives y ≤ -x/3 + 1
The base of the middle triangle is 3 and the base of the larger one is 6, so the larger triangle is twice the size of the middle one.
Multiply the height of the middle one by 2 to get the height of the larger one, which is labeled n.
n = 5 x 2 = 10
