(-2,8),(-1,5),(0,2),(1,-1),(2,-4) are points of the line.
Sarahtime (min) {3 } 5 12 17
distance (meters) {75} 125 300 425
Eva time (min) {2} 7 10 20
distance (meters) {52} 182 260 520
Sarah:meters over min =75 over 3 = 25 over 1
25 meters per min
Eva :meters over min= 52 over 2 =26 over 1
26 meters per min
eva is the faster swimming because 26 meters per min is faster then 25 meters per min .
i hope this help
Answer:
f(1) = -3 f(n) = 2 f(n - 1) + 1 f(2)
Alternate form:
{f(n) = -f(1)/3, f(n - 1) = f(1)/2 - f(2)/2}
