Answer:
slope = -
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 9, - 4) and (x₂, y₂ ) = (- 3, - 6)
m = =
= -

Answer:
200 litres
Step-by-step explanation:
let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is
g = kd ← k is the constant of variation
To find k use g = 25, d = 100 and s = 100, then
25 = k × 100 × = k × 100 × 10 = 1000k ( divide both sides by 1000 )
0.025 = k
g = 0.025d ← equation of variation
When d = 1000 and s = 64, then
g = 0.025 × 1000 × = 0.025 × 1000 × 8 = 200
