Sagot :
Solution :-
[tex]\textsf{The slope of a line passing through two}[/tex]
[tex]\sf{given \: points \:(x_1,y_1) \:and \:(x_2,y_2) \: is \:given \: by - }[/tex]
[tex]\green{ \underline { \boxed{ \sf{ Slope, =\frac{y_2-y_1}{x_2-x_1}}}}} [/tex]
Here,
- [tex]\sf{x_1= 9}[/tex]
- [tex]\sf{y_1=2}[/tex]
- [tex]\sf{x_2=9}[/tex]
- [tex]\sf{y_2= 27}[/tex]
Putting Values:-
[tex]\begin{gathered}\begin{gathered}\\\implies\quad \bf Slope =\frac{27-2}{9-9} \\\end{gathered} \end{gathered} [/tex]
[tex]\begin{gathered}\begin{gathered}\\\implies\quad \bf \frac{25}{0}\quad(not\: defined) \\\end{gathered} \end{gathered}[/tex]
>>The slope of the line that passes through the given points is not defined.
Note- We can conclude that if x-coordinate of the points through which line passes are same , then slope is always not defined .
