1. When John received his W2, he received several copies. Why was he sent multiple copies of this form?
Firlakuza [10]
<span>1. W2 is a form every empoyer send to his employees that reports the annual wagges of the employees and the amount of taxes. This W2 form is sent at the end of the year. The employees get at least two copies of this form. One copy is for the employee and the other is for IRS (Internal revenue Service) to report the wages. 2. John's employeer sent John the W-2 form. Every employer is obligated to deliver W2 form to all of his employees. John can get copy of the W-2 form for IRS (Internal Revenue Service). This is done for a fee. 3/ In order to know how much John did in wages in the 2014 we must have knowledge of John's salaty. Without this information we can not clculate the wages. </span>

Can someone please help ? :(
Anika [276]

Answer:

I'll list the answers as coordinates (just input the second number in each coordinate)

(-2, 11)

(0, 1)

(2, -9)

(4, -19)

Step-by-step explanation:

So you see how the x column is filled out? You plug in the numbers in each area and solve for y.

So we start off with -2. You take the x out and place -2 instead. Your equation should look like this:

y = -5 (-2) + 1

Next you multiply -5 and -2, giving you 10. Your equation would look like this now:

y = 10 + 1

Next you add 10 and 1 together, and you have your answer. Keep doing the same thing, but instead of -2 for x, use 0, 2, and 4.

Hope I helped! Have a nice day or night! ^-^
