Question

If y = 12 when x = - 15 find y when x = 2

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

Answer 2

Answer:

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
