Answer:
y=-4x-3
Step-by-step explanation:
y=mx+b
y=b=-3 ( y intercept is when x=0, then y=b=-3)
y=-4x-3

Answer:
Distance B = 1275 kilometers.
Step-by-step explanation:
Let the two distances and time be A and B respectively.
Given the following data;
Distance A = 17 kilometers.
Time A = 8 minutes.
Distance B =?
Time B = 60 minutes.
First of all, we would find the constant speed;
Speed = distance/time
Substituting into the equation, we have;
Speed = 17/8
Speed = 2.125 km/m
Now, to find the distance B;
Distance B = speed * time
Distance B = 2.125 * 60
<em>Distance B = 1275 km</em>
aerage rate of change is just the slope from the endpoints of teh interval
ie ![averagerateofchange=slope=\frac{f(5)-f(1)}{5-1}](https://tex.z-dn.net/?f=averagerateofchange%3Dslope%3D%5Cfrac%7Bf%285%29-f%281%29%7D%7B5-1%7D)
assuming you mean ![f(x)=480(0.3)^x](https://tex.z-dn.net/?f=f%28x%29%3D480%280.3%29%5Ex)
evalaute f(5) and f(1)
f(5)=480(0.3)^5=1.1664
f(1)=480(0.3)^1=144
average rate of change=(1.1664-144)/(5-1)=-35.7084
the average rate of change of the function on the interval x=1 to x=5 is -35.7084
