Option A:
The equation for the trend line is y = 82x + 998.
Solution:
The points on the line are (2, 1162) and (11, 1900).
Here, 
Slope of the line:



m = 82
Point-slope formula:



Add 1162 on both sides of the equation.

The equation for the trend line is y = 82x + 998.
Hence Option A is the correct answer.
