exploded diper , here u go... :D
Remember, this method is applicable to ALL transformations. All you need is, two points and there result under that specific transformation.
and if A makes A' under transformation X, then the second point you choose, B, must also make B' under transformation X.

*Adding*
And the transformation abcd can be found by multpliying the inverse of the matrix representing the Given points by the matrix of the Image points
(ie.)
(-1 -4) * (1 4)^-1
(3 2) (3 2)

View attachment 38839here is the vectors question answer
c) as we see the 2 lines CD and OB have a ratio between them i.e. 1:2
because 1/2 * x = CD and x = OB
where x = 3a + c
thus due to this ratio we conclude the two lines are parallel AND in the same direction.

but if we had CD = -1/2 * x , then the 2 lines would have been parallel BUT in opposite direction.
am i clear?

for the first part(i)a the s.f should be -2 because the image is double the size and negative because the image is behind p not infront it
for the second part (i)b you should join every vertex of triangle "P" where it belongs to triangle "q" after it had enlarged and the point where the three lines join should be the center of enlagment
for(ii) number 2 was a k which means any number when the matrix which has this k surrounding by two ones on the top right so it is a shear x-axis invariant and the k is the scale factor
ans also (iii) (b)..........
