Answer:
(b) x-axis
Step-by-step explanation:
You want the line of reflection that maps A(-4, -5) to A'(-4, 5).
The line of reflection is the perpendicular bisector of a point and its image.
Points A(-4, -5) and A'(-4, 5) both lie on the vertical line x = -4. The midpoint of that line is ...
M = (A +A')/2 = ((-4, -5) +(-4, 4))/2 = (-8, 0)/2 = (-4, 0)
Then the perpendicular bisector will be the horizontal line through the point (-4, 0). That line is y = 0, the equation of the x=axis.
The x-axis is the line of reflection, choice B.
