(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.
