Given n= 8 ∑ x = 1377 ∑ x2 = 98945 ∑ y = 1578 ∑ y2 = 126756 ∑ xy = 110579

What is the slope of the regression line?

a
50.73
b
159.45
c
104.96
d
204.25

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

what am i looking for finish the question.

step-by-step explanation:

y=foot

x=foram

a. easy, plug 17 for x and evaluage for y

y=0.860(17)+3.302

y=14.62+3.302

y=17.922 inches

b. rate of change is slope

y=mx+b

m=slope

so

rate or change is 0.860 inches per legnth of forarm

c. what data

d. it is a function

since it is 1st degree (no exponents greater than 1 on the placeholder), and it is not a vertical line

it is a function
