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

.

2 meters = 200 centimeters
Answer:
C) h(x)=-1.3-1.75x
Step-by-step explanation:
f(x)=3.7-2x
g(x) = 0.25x-5
f(x) + g(x) =3.7-2x + 0.25x-5
Combine like terms
= -1.75x - 1.3
