Joe can type 60 words per minute. How long will it take him to type a 4800-word essay?

80 minutes or 1 hour and 20 minutes

Since Joe can type 60 word per minute, divide 4800 by 60, you will get 80 minutes which is basically 1 hour and 20 minutes.

  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.
