Please help me: Use the information provided to write the equation of each circle:
9) Center: (13, −13) Radius: 4
10) Center: (−13, −16) Point on Circle: (−10, −16)
11) Ends of a diameter: (18, −13) and (4, −3)
12) Center: (10, −14) Tangent to x = 13
13) Center lies in the first quadrant Tangent to x = 8, y = 3, and x = 14
14) Center: (0, 13) Area: 25π

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

b.-4 units

all you   do is count how many times you move

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
