Question

In the following situations, is there likely to be a correlation? If so does the correlation reflect a causal relationship? Explain. the average daily winter temperature and your heating bill
A. There is a positive correlation. The higher the average daily winter temperature the higher your heating bill.
B. There is a negative correlation and a causal correlation. The higher the average daily winter temperature the lower your heating bill.
C. There is no correlation.

Answer 1

B, you use less heat in warmer temperatures

Answer 2

thanks what about Write an equation for the line that is parallel to the given line and passes through the given point. y = x + 8; (4, 10)

Answer 3

parallel --> same slope
point slope form of line
y - y1 = m(x-x1)
plug in your slope (m) and given point (x1,y1) = (4,10)

Answer 4

Write an equation in point-slope form for the line through the given point with the given slope. (8, 3); m = 6
A. y + 3 = 6(x - 8)

B. y - 3 = 6(x - 8)

C. y - 3 = 6(x + 8)

D. y + 3 = 6x + 8

Answer 5

which one

Answer 6

haha what happened to last question?
anyway i gave you general form, you pick which one

Answer 7

dnt get it

Answer 8

dont get what?
plug in 8 and 3 for x1 and y1

Answer 9

8/3

Answer 10

?

Answer 11

y - y1 = m(x-x1)
m=6
x1 =8
y1 =3
plug those values in

Answer 12

C. y - 3 = 6(x + 8)

Answer 13

how does (x-8) become (x+8)
its x - x1

Answer 14

if x1 = -8, then it would be (x+8)

x-(-8) = x+8
