The point (−4, −1) is reflected across the y -axis. What are the coordinates of the reflected point?

When a point is reflected across the y-axis, the x-coordinate is negated and the y-coordinate remains the same.

So, for the point (-4, -1), the x-coordinate becomes 4 (negation of -4) and the y-coordinate remains -1.

Therefore, the coordinates of the reflected point are (4, -1).
