Answer:
A) 4900
B) How far above she is before she starts hiking/the distance she is from the canyon floor.
Step-by-step explanation:
Since it's linear, it will follow the formula y=mx+c.
We can sub in the values to get:
3500=m(1)+c → 3500-m=c
2100=m(2)+c → 2100 = 2m+c
Sub '3500-m' in for c:
2100=2m+3500-m
m= -1400
c=3500-m=3500-(-1400)=3500+1400=4900
∴equation is: y= -1400x+4900
To find the initial value, ie when the number of hours = 0, we sub in zero for x:
y = -1400(0) + 4900
PART A ANS: 4900
PART B ANS: Since the number of hours passed is zero, the value represents how far above she is before she starts hiking/the distance she is from the canyon floor.
