Step-by-step explanation:
a) The variable replacing y is g
The units are gallons
b) The variable replacing x is t
The units are minutes
c) We compare this with the general form of a straight line equation
g = 4t + 8
compared with y = mx + b
so we can see that b is 8 here
Putting the units , the intercept is 8 gallons
This means that at zero minute, or initially , the amount of gas in the truck’s tank is 8 gallons
In other words, the amount of gas in the tank of the truck before it started refueling in the gas station is 8 gallons
d) The slope is 4 gallons/minute
What the slope represents is the filling rate
It is simply the amount of gallons entering the gas tank per minute as the gas tank is refueling
