Help and explain please :)))))))
WARRIOR [948]

Answer:

f(4.7) = 13.1

Step-by-step explanation:

essentially this is just 3x-1

plug in 4.7 for x... 3*4.7 = 14.1 then subtract 1 =

13.1

the issue is the || absolute value...

if the "X" x value is NEGATIVE in the problem, just remove the negative sign...

in other words f(-4.7)  = 3(4.7) - 1

Plug in the points:

m=\frac{-8+2}{6-4}=\frac{-6}{2}=\boxed{-3}

The slope is -3.

Hope this helps.
