The table below shows the relationship between the numbers of magazine subscriptions (x) two students have sold to raise money (y) for a field trip. What is function rule for this set of data?
x y
1 3
3 5
5 7
y = x + 1
y = x – 1
y = x + 2
y = x – 2

I am not 100% sure on what this question is asking but it seems like it is just asking for the correct equation of a line as shown by the given points. If that is the case, you will need to find the slope between any two points first. You can do that by choosing two points and saying slope(m) =( y2  y1)/(x2x1). I used the first two points and found that I had a positive slope of 1. I drew out the points on the graph and found that the equation of the line is y = x+2. The +2 just says that the graph intersects the y axis at positive 2. Hope that helps
