Plz help with the question below, ur amazing thx plz

IT would be the bottom right one. I sat this because the equation y=x+9 means you are adding 9 to the x-value and 1+9=10 and the bottom right one represents that and all the other's have either (1,9), or (1,8). So the bottom right one is the correct answer because none of the others represent this equation. Hope this helps
