An addition doubles fact that can help me find 4 + 3 is 3 + 4. I know because 4 + 3 is the same as 3 + 4 and if I know 3+4 I know 4 + 3 because of the communitive property. (Thats what my teacher told me what was correct)
I think its B , because if you connect the TWO dots forming a triangle its 3 up and 4 to the right making 3/4 as the slope and the Y intercept is 1 so y=3/4x +1
