Look at the table of values below.

x y

1 - 1

2 - 3

3 - 5

4 - 7

Which equation is represented by the table?

y = - 2x + 1

Step-by-step explanation:

The amount from - 1 to - 3 is - 2

The amount from - 3 to - 5 is - 2

The amount from - 5 to - 7 is - 2

So you can conclude that 2 is being subtracted each time, but you still have to find what the value for number zero is so you add 2 to - 1 and you get 1

So the equation is y = - 2x + 1
