Answer:
so 
Explanation:
The question is not much to go on with but I believe the m symbol is denoting gradient and that you're trying to find the second point.
In the first question m= 1/2, (6,0)
gradient formula(m):

so we are able to substitute one of the points:

so then it's like:
0-y2 = 1
-y2 = 1
y2 = -1
and 
6-x2 = 2
-x2 = -4 
x2 = 4
so then a possible point would have been (4,-1) and (6,0) which has a gradient of 1/2
(I'm not sure if this is the answer)
