## Sagot :

**Answer:**

A'=(-9, - 3)

**Step-by-step explanation:**

A' will be 3*(the coordinates of A), A'=(-9, - 3)

**Coordinates **of **A'** are given by **(-9,-3).**

### What is Coordinates?

**Coordinates **of a point suggest the **position **of that particular **point **in the **Cartesian Plane**.

If the coordinates of a point are **(x,y) **then **x **is the **distance **of the **point **from **Y-axis **and **y **is the **distance **from the **X-axis**.

Here in the given graph, we can see that the **coordinates **of **A** of **quadrilateral **ABCD are **(-3,-1) **

ABCD is **dilated **by a factor of **3**.

So the **coordinates **of the **A'** which is the point **A** after dilating by **3** are given by the **product **of **3** and corresponding **original coordinations**.

Hence the **coordinates** of **A' **are = (3*(-3),3*(-1)) =** (-9,-3)**
