1. The problem asks to find the coordinates of a point whose abscissa (x-coordinate) is -4. 2. The abscissa is the x-value of a point in the Cartesian coordinate system. The ordinate is the y-value. 3. Since only the abscissa is given as $-4$, the point can be any point on the vertical line where $x = -4$. 4. Therefore, the coordinates of the point can be written as $(-4, y)$ where $y$ can be any real number. 5. Without additional information about the ordinate, the point is not uniquely determined but lies on the line $x = -4$. Final answer: The coordinates are $(-4, y)$ where $y$ is any real number.
