My question is in the screenshot.

26 4/5

33.5÷1.25=26.8

67/2 × 4/5

67×4=268

2×5=10

268/10=26 4/5

I hope this helps:

b. astronomers

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
