2. A linear model for the data in the table is shown in the scatter plot. x 1 2 4 5 6 7 8 9
y 25 24 15 12 11 13 6 4

(a) Which two points should you use to find the equation of the model? Explain.

(b) Use the two points you chose in Part (a) to find the slope of the linear model, leaving your slope in fraction form. Show your work.

(c) What is the equation of the linear model in point-slope form?

(d) Rearrange the equation you wrote in Part (c) into slope-intercept form. Show your work.

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.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
