Chapter 1, Equations and Graphs - Section 1.1 - The Coordinate Plane - 1.1 Exercises - Page 93: 52

See below.

a) We must multiply the x-coordinate by $-1$. Thus it will become $(-3,7)$ b) We must multiply the x-coordinate by $-1$. Thus it will become $(-a,b)$ c) We must divide the x-coordinate by $-1$. Thus $(4,-1)$ is reflected to it. d) We must multiply the x-coordinate by $-1$. Thus they will become $A'(-3,3),B'(-6,1),C'(-1,-4)$
