Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, </em><em>b</em><em>)</em>
<em />
The fromual of a slope:
<em>(x₁, y₁), (x₂, y₂)</em><em> - points on a line</em>
<em />
We have the points from the graph:
(0, 1) → <em>b = 1</em> and (3, 3).
Calculate the slope:
Finally we have the equation of a line:
<u>Answer:</u>
- 3120 litres of fuel are required to fill the tank.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Quarter of tank = 1/4 x tank
- Volume = 1.6 x 2 x 1.3
- 1 cubic metre = 1000 litres
<u>Work:</u>
- Volume = 2 x 1.3 x 1.6
- => 4.16 m³
- => 4.16 x 1000
- => 4160
- => Quarter of tank = 1/4 x tank
- => 1/4 x 4160
- => 1040 L
- => 4160 - 1040 = Required fuel (In litres)
- => 3120 = Required fuel (In litres)
Hence, <u>3120 litres of fuel are required to fill the tank.</u>
Hoped this helped.
