You question isn't clear, but I assume that you are asking for the slop of a line parallel to y=-(5/4)(x)+7.
The line parallel would have a slop of -5/7 and the line perpendicular would have a slop of 5/7.
The difference between the two answers is the sign of the two slopes, one is positive the other is negative
Aaron's plane flew 2.25 cm More than noah's plane
5.14- 3.89 = 1.25 1.25/ 0.25 =5 m=5 I think, you might want to check it :)
The answer is 3.85555556 because the ratio is 9:1 the length 34.7 so that means the length will be 9 times the width so you divide.
If i am not mistaken , the y-int is 2
