B) dilate the smaller circle by a scale factor of 9.

C) rotate the larger circle 270º.

D) reflect the smaller circle in its diameter.

B) dilate the smaller circle by a scale factor of 9

Step-by-step explanation:

y= 3/5x + 4/5

Step-by-step explanation:

First, write your current equation: y=3/5x+b. Next, plug in your coordinate to the equation. It should look like this: -1=3/5(-3)+b. Multiply 3/5 by -3 to get -9/5. This is what you should have: -1= -9/5+b. Add 9/5 to both sides to get 4/5 as your y-intercept. Go back to your original equation and plug in 4/5 to b. This is your final equation: y= 3/5x + 4/5. Hope this helped!
