Help plzzz I don’t know how to do this but I am supposed to be writing the equation of the line above in point slope form

y - 1 = 2 ( x - 1 )

Step-by-step explanation:

y-intercept: (0 , -1)

point one: (1 , 1)

m = y2 - y1 / x2 - x1

-1 - 1 / 0 - 1

-2/-1

m = 2

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

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.
