Answer:

The coordinates of point B' are (3, 9)

Step-by-step explanation:

If the point (x, y) translated by a vector <a, b>, then its image is (x + a, y + b)

Let us use this rule to solve the question

In Δ ABC

∵ The coordinates of vertex A are (1, 3)

∵ The coordinates of vertex B are (2, 5)

∵ The coordinates of vertex C are (5, 3)

∵ Δ ABC is translated by the vector <1, 4>

→ By using the rule above add the x-coordinate of point B by 1

   and the y-coordinate of point B by 4

∴ B' = (2 + 1, 5 + 4)

∴ B' = (3, 9)

∴ The coordinates of point B' are (3, 9)
