At 0km she had 58𝑙 (0,58) and at 464km she had 0𝑙 (464,0)
V/58 + d/464 = 1 so V(d) = 1/8 d + 58
d(V) = 464  8V so when 12𝑙 remain Jana has traveled 464  8*12 = 368km
(and has 8*12 = 96km to empty the tank)

If Jana is driving the vehicle at a constant speed, it volume of gas that it burns each mile will be constant. To determine this number, use the following equation.
V = k * d
58 = k * 464
k = 58 ÷ 464 = 0.125 L/km or ⅛ L/km
Determine the distance traveled when 12 L of gas is left
V = 58 – 12 = 46
46 = 0.125 * d
d = 368 km
I hope this is helpful for you.

i) Consumption = 58L/464km = 1/8 L/km
V = 58  d/8
ii) 12 = 58  d/8
d = 368 km

With d = 0, the tank is 58L, so we have one data point: (0, 58)
Then after 464 km, the tank is empty, so this data point is: (464, 0)
To get the equation between the points we need to find the slope first which is the change in y over the change in x:
m = (58  0) / (0  464)
m = 58 / (464)
m = 1/8
Then we have the intercept already from the first data point:
b = 58
So the equation is:
V = (1/8)d + 58
For the volume of gas remaining after "d" km has been driven.
What's the distance traveled with 12 L of gas remains? Solve for d when V = 12:
12 = (1/8)d + 58
46 = (1/8)d
46(8) = d
d = 368 km
