Step-by-step explanation:
(5,2) & (10,-3) 
the slope of the points are 
y2 - y1 / x2- x1 
-3-2/10-5 
-5/5 
-1 
the mid point of the given points are
x= x1 + x2/2 , y= y1 +y2 /2 
.
.
.
.
( , )
the equation of the line that passes through the given points are as 
y+ y1 = m (x+ x1) 
:. now put the value of the mid point in y1 and x1 and the value of slope in m 
also find the mid point, it's hard to do it in a mobile without calculator and paper and pen
