On a road map, the distance between 2 cities is 2.5 inches. the map scale is 1 inch: 30 miles. what is the actual distance between the cities?

75 miles.

Step-by-step explanation:

By proportion the actual distance is 2.5 * 30

=    75 miles

  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.
