Question 420019
.
What is the slope-intercept form that contains the points (3,7) and (3,5)
~~~~~~~~~~~~~~~~~~~~~~~~~~~



The solution and the answer in the post by @mananth both are incorrect.



To solve correctly, notice that x-coordinate is the same for both points.


Therefore, the equation of the line is  x = 3.


It is a very special case, when the line is vertical.


In this case, the slope is not defined and the slope-intercept form does not work.


In this case an equation of the line is  x = 3.



Solved correctly.
