Question

Choose the graph of the function f(x) =1/2 x - 2. Click on the graph until the correct graph appears.

Answer 1

Answer with explanation:

The given function is

     $y=\frac{x}{2}-2$

→2 y = x-4

→x -2 y -4=0

The function represents Linear function.

To plot the linear function on x y plane, we will write function in the form of slope intercept form, which is as follows

       $\frac{x}{a}+\frac{y}{b}=1\\\\\frac{x}{4}+\frac{y}{-2}=1$

So, the graph will cut X axis at , (4,0) and (0, -2).

To draw a unique line we need two points . The unique line will pass through (4,0) and (0, -2).

Answer 2

The correct answer would look something like this:
