Answer:
y = 1/3x -1
Step-by-step explanation:
Let’s look at this in y = mx + b form. b is the y-intercept and we see that it intersects with the y-axis at (0,-1), so b = -1. The slope is 1/3 because for every 3 units it ”runs,” it rises by 1, so m = 1/3. Substituting, we get: y = 1/3x -1.

Answer:
a) 1/7 liters of petrol is used for each mile
Step-by-step explanation:
Justin fills his car with 40 litres of petrol. After travelling 35 miles it's down to 35 litres.
From the above statement:.
The difference is :
40 litres - 35 liters = 5 liters
Hence:
After travelling 35 miles he used 5 liters
(a) How much petrol does the car use each mile?
This is calculated as:
35 miles = 5 Liters
1 mile = x liters
Cross Multiply
35x = 5 Liters
x = 5/35
x = 1/7 liters
Hence, for each mile, 1/7 liters of petrol is used
