Denise has a prepaid cell phone. This month she would like to purchase a $9 message package. The rate plan for the talk time is $0.10 per minute. What is the maximum amount of talk time that Denise can purchase for her bill to stay under $45? (Need the Equation)

  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.
