Answer:

Option B

Step-by-step explanation:

Option A is a representation of the equation because the coordinates of the points in the line satisfy the given equation. For example the point (0, -2) because when x = 0, y is equal to -2:

y= 0.5x - 2

y = 0.5(0) - 2

y = 0 - 2

y = -2

For Option B, we need to prove that when we replace the values of x in the equation, we get the values of y.

So, if x = -4, y is equal to:

y = 0.5(-4) - 2

y = - 2 - 2

y = -4

If x = -3, y is equal to:

y = 0.5(-3) - 2

y = - 1.5 - 2

y = -3.5

Since the second row of the table is doesn't have the values x = -3 and y = -3.5, this option is not a representation of the equation.

Therefore, the answer is Option B.
