Answer:
275.
Step-by-step explanation:
The gradient of the graph is 70/2 = 35 and it passes through the origin so we can write its equation as
y = 35x.
The gradient of the function represented by the the table is
(240-180) / (4-3) = 60
Ehen x = 3 y = 180 so when x = 0 y = 180 - 60 - 60 - 60 = 0 and the equation of this function is
y = 60x.
For the first equation when x = 11, y = 35*11 = 385.
For the second it is 60 * 11 = 660
So our answer is 660 - 385
= 275
