a) y=3.75(x-1)+0.65
b) y=3.75-0.65(x+1)
c) y=3.75+0.65x
d) y=3.75+0.65(x-1)

and how did you get that answer

Circle a has center of (2,3) and a radius of 5 and circle b has a center of (1,4) and a radius of 10. what steps will show that circle a is similar to circle b 1) dilate circle a by a scale factor of 2 2) translate circle a using the rule (x+1,y-1) 3) rotate circle a 180 degrees about the center 4) reflect circle a over the y-axis
