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 
then the general form
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
