1. create a scaled copy of abcd using a scale factor of 4.

Explanation:

Step1: Identify coordinates of ABCD

Assume A(x1,y1), B(x2,y2), C(x3,y3), D(x4,y4) from the grid.

Step2: Apply scale - factor formula

For a point (x,y) and scale factor k = 4, the new coordinates (x',y') are given by x'=kx and y'=ky. Calculate new coordinates for A, B, C, D.

Step3: Plot new points

Plot the new points A', B', C', D' on the grid to form the scaled - copy of ABCD.

Answer:

Plot the new points obtained by multiplying the x and y coordinates of each vertex of ABCD by 4.
