Question

6 - point p is the midpoint of segment ab. Co-ordinates of p are (3 , 1) and b are (5, -4). What are the co-ordinates of point a?

Answer 1

Answer:

Step-by-step explanation:

let co-ordinates of a be(x,y)

as midpoint between two point is given by ( (x1+x2)/2,(y1+y2)/2 )

so ,

x+5/2=3

x+5=6

x=1

y-4/2=1

y-4=2

y=6

point a is (1,6)
