Question

Each column of the matrix represents a vertex of a triangle. If Rosa scales the triangle by finding 3T

Answer 1

`\{(0,0) (0,9) (9,0)\}`

Explanation:

Given

See attachment for matrix

From the attachment, we have the following vertices

`(x_1,y_1) = (0,0)`

`(x_2,y_2) = (0,3)`

`(x_3,y_3) = (3,0)`

When scaled by 3T, we have the following:

`(x_1,y_1) =3 * (0,0)`

`(x_1,y_1) =(0,0)`

`(x_2,y_2) = 3 * (0,3)`

`(x_2,y_2) = (0,9)`

`(x_3,y_3) = 3 *(3,0)`

`(x_3,y_3) = (9,0)`

Hence, the vertices are:

`\{(0,0) (0,9) (9,0)\}`
