Answer 37

very close

Answer 38

notice that they associate the 29 with the y

Answer 39

and the 6 with the x

Answer 40

yea

Answer 41

and also rememeer that slope is:
change in y/change in x

Answer 42

so it will be -7/2 not -2/7

Answer 43

does that make sense?

Answer 44

oh yea i was so closed

Answer 45

yep

Answer 46

correct all the points on that line always have a y value of -3

Answer 47

y is always -3

Answer 48

HOY -- horizontal line, 0 slope, represented by y = a number

Answer 49

thanks
