37.5 feet

Step-by-step explanation:

it says it has a ratio of 1:30. 1 inch = 30 feet, so break it down. 1.25 in. 1 in =  30 ft, so there is 30 ft. the 0.25, well 0.25 times what = 1 whole? 4, so if 30 is the 1 whole, you have to devide 30 by 4, which is 7.5, so then you just add 30 to 7.5

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
