Answer: b
Explanation:
The line of best fit to a scattergram is obtained in linear regression analysis by minimizing the sum of the squared errors.
For example, in the diagram shown below, there are n data points in the scattergram.
The error for the i-th data point is

.
The coefficients (a and b) for the line of best fit are determined using calculus, to minimize

.
Linear graphs:
1, 4, and 6
Non-linear graphs:
2, 3, and 5
Explanation:
Linear graphs are straight line, non-linear graphs are not straight lines.
Answer:
75.062c
Step-by-step explanation:
To find the missing side use pythagorean theorem
So 
Solve for b, b= 6.021
To find the area use
bh
So
(6.021+19)(6)= area
And you get 75.062
