The statement "That does not extend in both directions." will make the definition, precise.
Kevin's line segment definition is correct.
However, the end points in a line segment implies that the line segment does not extend past its two end points.
So, to make it precise;
Kevin needs to include that the line segment does not extend in both directions, in the definition.
Hence, option (c) is correct.

Number of solutions: no roots
Type of solution: Not Real
Step-by-step explanation:
We need to identify the number of solutions and their types using the discriminant.
We are given: 
Rearranging:

Discriminant can be found by: 
where b=-40, a=10 and c=41
Putting values:

So, Discriminant is -40
If the discriminant is less than zero i.e -40 then there are no real roots.
So, Number of solutions: no roots
Type of solution: Not Real
Keywords: discriminant
