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
