(3,7) and (3,5)
slope m = (y2-y1)/(x2-x1)
m= 0

Plug value of one point and the slope in -(4,5 )
Y = m x + b
5 = 0 + b
b= 5

So the equation will be
Y = 5

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.
