Answer:

   (a)  f(x) = -2x + 4

Step-by-step explanation:

The point (0, 4) in the table tells you the y-intercept is 4. Then the equation in slope-intercept form will be ...

  y = mx +b . . . . . m is the slope; b is the y-intercept

The answer must have the form ...

  y = mx +4

Only the first choice has the correct y-intercept.

__

You may notice that when x gets larger by 1, y decreases by 2. That means the slope is m = Δy/Δx = -2/1 = -2. Then the whole equation is ...

  y = -2x +4
