The answer to this problem would be B because your going up by 6
0.4%, turn it into a decimal, which is 0.004
0.004*100= 0.4
the slope is -4, so B is the answer.
46 1/4% = 46.25/100 = 23.125/50
I can't remember if this is correct or not but I believe it would be 5 multiplied by 20 plus 6. As I said I don't Know for sure if this is correct or not. However, I hope it help
