I believe the answer is A : y=2x+1
Explanation: The Y-intercept goes through 1 not -1 so you know the last part will be +1. That limits it to A and B. Secondly, It goes rise/run. So look at how the line goes through points. For example From the intercept to the next line. It goes up 2 over one. So 2/1 which is 2. This way it is Y=2x+1! Hope this helps!
