Answer
See below.
Work Step by Step
a) We must add $3$ to the x- and $2$ to the y-coordinate. Thus it will become $(5+3,3+2)=(8,5)$
b) We must add $3$ to the x- and $2$ to the y-coordinate. Thus it will become $(a+3,b+2)$
c) We must add $3$ to the x- and $2$ to the y-coordinate. Thus it will become $(-3+3,0+2)=(0,2)$
d) We must add $3$ to the x- and $2$ to the y-coordinate. Thus they will become $A(-2,1),B(0,4),C(5,3)$
