Answer:

(3,1)

Step-by-step explanation:

let B be (x,y)

m(1,3)=midpoint

A(-1,5)=(x1,y1)

B(x,y)=(x2,y2)

(1,3)= x1+x2/2          y1+y2/2

(1,3)= -1+x/2           5+y/2

so,

-1+x/2=1              5+y/2=3

-1+x=2                 5+y=6

x=3                      y=1

therefore the co ordinates of B(x,y) are (3,1)
