The length of an unsharpened pencil is 7.5 inches. how many pencils would you need to lay end to end to circle the earth once? assume the radius of the earth is 6300 km

step-by-step explanation: yes

  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.
