Question

if scaling in x co-ordinate by factor 4 in applied on the point (2,1)then it transform to...​

Answer 1

Answer:

$\huge\underline{answer}$

1. Make a 2x2 scaling matrix S as:

Sx 0

0 Sy

2. For each point of the polygon.

(i) Make a 2x1 matrix P, where P[0][0] equals

to x coordinate of the point and P[1][0]

equals to y coordinate of the point.

(ii) Multiply scaling matrix S with point

matrix P to get the new coordinate.

3. Draw the polygon using new coordinates.
