Answer:
C' (-4 , 2)
slope of new line = line "L" = -2
Step-by-step explanation:
C (x₀,y₀): (0,2) dilation center (h,k): (2,2) scale factor (sf): 3
C' (x,y)
x = 2 + 3*(0-2) = -4 x = h + sf*(x₀ - h)
y = 2 + 3*(2-2) = 2 y = k + sf*(y₀ - k)
C' (-4 , 2)
slope of new line = line "L" = -2
Answer: (x - 3)² + y² =
<u>Step-by-step explanation:</u>
Circle Formula: (x - h)² + (y - k)² = r² ; (h, k) is the center & r is the radius
Use the distance formula for (3, 0) and (1, )
****************************************************
Center (h, k) = (3, 0) Radius (r) =
(x - h)² + (y - k)² = r²
(x - 3)² + (y - 0)² = ()²
(x - 3)² + y² =
