## dajapeay 3 years ago 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.

B, you use less heat in warmer temperatures

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)

3. dumbcow

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)

4. dajapeay

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

5. dajapeay

which one

6. dumbcow

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

7. dajapeay

dnt get it

8. dumbcow

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

9. dajapeay

8/3

10. dumbcow

?

11. dumbcow

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

12. dajapeay

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

13. dumbcow

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

14. dumbcow

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