A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How can a line of best fit be useful?

It is very useful and interesting to be able to enter data for two variables, graph those points in a scatter plot, and then generate a line of best fit through those points. From the line of best fit, it is fairly simple to generate a linear equation. A line of best fit is drawn through a scatterplot to find the direction of an association between two variables. This line of best fit can then be used to make predictions.


What does a line of best fit tell you about data on scatterplot?

It tells you that if there were a linear relationship between the two variables, what that relationship would look like and also how much the observations differed from that linear fit.

What is a linebest fit in a scatterplot?

It is a line that passes through or nearly passes through the plotted points on the coordinated grid.


Is the best fit line the same as the line of best fit?

Yes but phrased differently


Why does the line of best fit have to start from 0?

The line of best fit does not have to start from 0.


What is a line of best fit on a line graph?

The line that minimized the sum of the squares of the diffences of each point from the line is the line of best fit.


What is a line that is not a line but is almost a line?

A line of best-fit.


Why does best fit line does not touch all data points?

Because the "best fit" line is usually required to be a straight line, but the data points are not all on one straight line. (If they were, then the best-fit line would be a real no-brainer.)


Why is a best fit line used?

The line of best fit is the best possible answer you can get from raw data. They also can be used to make predictions.


What is the process of finding line of best fit called?

Finding the line of best fit is called linear regression.


Does the line of best fit have to start from the origin?

The line of best fit does not have to pass through the 0 (origin) and rarely does
