Based on the description of the graph you provided, it appears that it is a horizontal line representing the equation \( y = 4 \) since you have mentioned that there are points (0,4) and (0.5,4) both on the curve.
Thus, the solutions to the graph would be:
- y = 4 (This is the correct equation since the graph represents a horizontal line at y=4.)
The other options refer to specific x-values, which do not relate to the graph or satisfy the equation \( y = 4 \) (since the line is horizontal and does not intersect the y-axis at any point besides 4). Therefore, the other responses (x = 4, x = 3, x = -3, and x = -4) do not apply.
So, the only correct response is:
- y = 4
