Answer:
Option B and D are correct.
Step-by-step explanation:
Given: A line passes through the points (2,4) and (5,6).
* Case 1: 
If a line passes through the points (2, 4) and (5, 6) 
Point slope intercept form: 
for any two points  and
 and 
then the general form  for linear equations where m is the slope given by:
 for linear equations where m is the slope given by:

First calculate slope for the points (2, 4) and (5, 6);

then, by point slope intercept form;
 
 
* Case 2: 
If a line passes through the points (5, 6) and (2, 4) 
First calculate slope for the points (5, 6) and (2, 4);

then, by point slope intercept form;
 
 
Yes, the only equation of line from the given options  which describes the given line are;
 and
  and
