You can estimate that 5x4257 is 20,000
to check 5x4257=21,375 which is close to 20,000
F(x)=4x-8
f(x)=y=4x-8
f^-1(x)=?
x=4y-8
x+8=4y
f^-1(x)=y=1/4x+2
Answer:
Line B
Step-by-step explanation:
I found the slope of Line B, it was -2, by looking at the distance rise/run between two points in the line.
Hope this helps. :)

Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (1, 6)
m =
=
=
= 2
