Answer:
Explanation:
Vertices of the given triangle ABC are A(-1, 4), B(-1, 1) and C(-3, 1)
Equation of the mirror line → y = x
Rule to reflect these vertices over the mirror line y = x,
(x, y) → (y, x)
Therefore, image points of the vertices will be,
A(-1, 4) → A'(4, -1)
B(-1, 1) → B'(1, -1)
C(-3, 1) → C'(1, -3)
Now we can plot these image points to get the image triangle A'B'C'.
