Yes but phrased differently
Yes, technically a curved line can be a line segment, a line in general is something that can be curved or straight
A line of best-fit.
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.)
Plot straight line or curved graphs on the Cartesian plane Plot a line of 'best fit' for any correlation of given data Solve simultaneous equations when the coordinates intersect each other Transformations
one is straight and one is curved simple
Many sets of data do not form into straight lines. If by "What if" you mean how to plot a line onto this graph. Then simply draw a curved line of best fit.
A curved line is a line that is curved.
The line of best fit does not have to start from 0.
Yes but phrased differently
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 the difference between a trend line and a line of best fit
a curved line is a line that is bent without angels
