The table that shows a ratio of y to x as 8:1 is C.
This comes from the fact every value of y is 8 times the value of x given.
Yes it makes it a true statement because if my math is correct it will add up and the negative is not canceled. That’s only with multiplication
The answer would be:
8 × 4 = 32
32 ÷ 4 = 8
Change 25% to .25. Multiply .25 by 50 to get 12.5. Subtract 12.5 from 50 to get $37.50
The fromula of a slope:

a) (-1, -8), (-7, -4)
substitute

b) (2.1, 3.8), (3.1, 7.6)
substitute
