Aline of fit might be defined as
question 1 options:
a)
a vertical line halfway through the data.
b)
a line that might best estimate the data and be used for predicting values.
c)
a line that connects all the data points.
d)
a line that has a slope greater than 1.

a line that might best estimate the data and be used for predicting values.

Choice B is correct

Step-by-step explanation:

A line of fit might be defined as;

a line that might best estimate the data and be used for predicting values.

This line connects most of the data points thus minimizing the squared residuals of the regression.

I hope this helps...

A line of fit might be defined as:

b)  a line that might best estimate the data and be used for predicting values.

Step-by-step explanation:

Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points.

Line of best fit is actually a good approximation of data and is used to predict values on the graph.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
