If your trying to find the unit rate or the scale of the map, you need to figure out how many kilometers are per centimeters. To get that you need to do 63 divided by 9, witch would get you 7. So to my ability, the answer would be 1 cm per 7 kilometers. Hopefully this answer helped you and I'm hoping its correct.
4 over 7 because, she takes away a rose card from the total 8 cards she has, but also takes away a card from the total amount of cards.
Then again, I might be wrong :P
Y = mx + c is the general equation of a line. m is the slope and c is the y intercept, by substituting these values in you get y = 1/4 x -2
Area = length x width
96 = length x 8
Length =96/8
Length = 12 metres
