Answer:
slope = - 
Step-by-step explanation:
given f(4) = 6 and f(- 2) = 8 , then 2 points on the line are
(4, 6 ) and (- 2, 8 )
calculate slope m using the slope formula
m = 
with (x₁, y₁ ) = (4, 6 ) and (x₂, y₂ ) = (- 2, 8 )
m =
=
= - 
3.25 x 25% = .81
3.25- .81 = $2.44
$2.44 is the sale price
2 x 2 x 5 x 5 x 5
2^2 x 5^3
