Donavan · Answer 1

To find y, when x = 2

we set up another ratio y/2

By the definition both ratios are equal 12/-15 = y/2

Multiple to each side by 2.

12*2/-15 = 2y/2

8/-5 = y

y = - 8/5

Thumper · Answer 2

With the information given

on a scale of (12/-15) or - 0.8. Meaning y is - 8 tenths of x

so - 0.8x2 = - 1.6

Answer: y = - 1.6
