You have to convert feet to centimeters here. change 102 feet to inches by multiplying by 12. Then convert inches to centimeters. 1 inch = about 2.5 cm, so divide the inches by 2.5 to get centimeters. Then take a ratio with the 12 cm. I think the scale is 40:1.

yeah for 2 but when I tried that for x = 8, I have a huge gap between the two numbers for 8. I got between x=0 and x =8, it is -88. then dividing that by 8, i got -11. then when i did between x= 8 and x =10, i got -55. then dividing that by 8, i got -1.875 and now I'm stuck
