Triangle ABC is given by the points A(1, 1), B(3, 2), and C(2, 3). Find the rule of transformation if the image has points A′(2, 2), B′(6, 3), and C′(4, 4). A (x, y) → (2x, y)
B (x, y) → (2x, y + 1)
C (x, y) → (2x, 2y)
D (x, y) → (x, y + 1)

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

correct choice is a

step-by-step explanation:

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is
