Answer:
f(-4) = -12
Step-by-step explanation:
![f(x)=2x-4](https://tex.z-dn.net/?f=f%28x%29%3D2x-4)
To calculate f(-4), we need to substitute x in our equation above with -4:
![f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12](https://tex.z-dn.net/?f=f%28x%29%3D2x-4%5C%5Cf%28-4%29%20%3D%202%2A%28-4%29%20-%204%5C%5Cf%28-4%29%20%3D%20-8-4%20%3D%20-12)
Note that 2*(-4) = -8

Answer:
A
Step-by-step explanation:
Let's try choice A.
y = -5x-4
(10, -52)
-52 = -5(10)-4
-52 = -50-4
-52= -54
-52 is not equal to -54, so A is the answer.
