Veronika [31]
Well, because it is two years, 50x2 is 100 so 1000+100=1100

Then, you would do .25x1000 which is 2.5. That would mean you get 2.5 dollars back every month. 

Therefore, your answer is...

(3,2) and (4,9) = y=7x-19 or y=7x+21
Mumz [18]

When solving for this problem, replace x with the first coordinate and solve. if the answer is what you have for the second, it is correct. The first number in an ordered pair is your x and the second is your y. So I would rewrite the equation like this and solve.

          y=7x-19                                            y=7x+21

2=7(3)-19         9=7(4)-19                2=7(3)+21       9=7(4)+21    

2=21-19            9=28-19                 2=21+21          9=28+21

2=2                   9=9                       2=42               9=49

as you can see it is the first equation.
