Question

find co-ordinates of midpoint joining (1,2) and (3,-4).

Answer 1

Step-by-step explanation:

Explanation

We needed to find the coordinates of the midpoint of the two points (1,2) and (3,-4)

Theory

To find the coordinates of the midpoint of two points , we need to add the x coordinates and divide by 2 , and add the y coordinates and divide by 2

Calculation

Let P=(1,2) and Q=(3,-4)

The midpoint is given by

Let midpoint be R

Then. X= (1+3/2) Y=(2-4/2)

R=(2,-1)

Answer 2

Answer:

(2, - 1)

Step-by-step explanation:

$a(x,y) = (1,2)$

$b(x,y) = (3, - 4)$

$m(x,y) \: be \: midpoint$

$m = \frac{a + b}{2}$

$m(x,y) = ( \frac{1 + 3}{2} , \frac{2 - 4}{2} )$

$m(x,y) = (2, - 1)$
