Help. Please and thanks.

Answer 1

(2,6)

Explanation:

What is a dilation?

A dilation is a type of transformation that resizes an object.

To apply a dilation ( find the coordinates of a point after a dilation ) you must multiply the x and y values of the coordinates by the scale factor

Applying the dilation rule

We want to find the coordinate of vertex B after a dilation with a scale factor of 2. To do so we multiply the x and y value of vertex b by the scale factor or 2

Current coordinates of the triangle :

• A(1,1)
• B(1,3)
• C(3,1)

Coordinates after dilation

A' = (1,1) ===> (1×2,1×2) ===> (2,2)

B' = (1,3) ===> (1×2,3×2) ===> (2,6)

C' = (3,1) ===> (3×2,1×2) ===> (6,2)

The coordinate of the vertex B after the dilation is (2,6)
