Helpp!!! Mathematics⁉️⁉️⁉️ Look at the picture above

1. A 20 m length of rope costs £14.40.
(a) What is the cost of the rope, per metre?

(b) Calculate the cost of 12 m of rope.

ASAP !​​

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
