The relationship between the distance run and time
for Kofi can be represented by the equation

Bella
Kofi
which two equations could be used to
represent this relationship for Bella and
Elsie?
Distance (yards)
Elsie
Time (seconds)
A. Elsie: y = 12.75x Bella: y = 13.25x
B. Elsie: y = 16.55x Bella: y = 13.25x
C. Elsie: y = 12.75x Bella: y = 17.88x
D. Elsie: y = 16.55x Bella: y = 17.88x
