Answer:
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
