Question

Point P (-2, 5) is the midpoint of segment AB. Co-ordinates of A are (-5, y) and B are (x, 3). What is the value of x?

A) 1 B) -1 C) 2 D) -2

Answer 1

Answer:

x=1 is the answer

Step-by-step explanation:

as we know from section formula,

coordinates of mid-point of a line joining 2 points

(x1,y1) and (x2,y2) is:

x-coordinate of mid-point = (x1 + x2)/2

y-coordinate of mid-point = (x1 + x2)/2

according to this your question,

-2 = ( -5 + x ) /2

=> x-5=-4

=> x=1

I hope this helps
