The midpoint of line AB is M(-6,2). if the coordinates of A are (-5,-2), what are the coordinates of B?

The co-ordinates of B are (-7,6)

Step-by-step explanation:

Step 1 :

Given

Mid point of the the AB is M (-6,2)

A = ( -5,-2)

Let the point B be (x,y)

where x is the co ordinate of x  and y =  co ordinate of y

Step 2 :

The x co-ordinate of a line segment's midpoint obtained by adding the x co-ordinate of its end point and dividing by 2.

The y co-ordinate of a line segment's midpoint obtained by adding the y co-ordinate of its end point and dividing by 2.

Since  M is the mid point, we have.,

 = -6  and    = 2

so, -5 + x = -12

x = -7

-2 + y = 4

y = 6

Step 3 :

Answer :

The co-ordinates of B are (-7,6)

the answer to the question is a  

it has the same slope and the same y-intercept.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
