You are asked to write an equation for the line of best fit for the scatter plot shown without the use of a graphing calculator. What should you do first?

Find the slope using (1.2) and (9.12)
Find the slope using (4.6) and (5.81
Decide which two points give the most representative straight line.
Connect the points together

-6

Step-by-step explanation: Use the slope formula, its:

y^2-y^1

x^2-x^1

the 1 and 2 are your start points and endpoints. They are no actual exponents

it is c, trust i got your back lol

step-by-step explanation:

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.
