Hope that helped!
Two significant Figures I believe because you want to go with the least amount of sig figs that are already in your problem which would be 2 in 7500 because the zeros are not significant
There are multiple answers, you would need to know some of the other variables. Just do this. 70 - ( y * b) = r
Looks like the graph decreases so i think it is B <span />
