Point M is at (-2,-9) The point is reflected across the y-axis,

Then rotated 180° about the origin,

And finally translated 3 right and 2 down.

What are the new coordinates of the point?
A
(2,-9)
B
(3,6)
C
(-2,9)
D
(1,7)

only 10/60 isn't equivalent

hope this : )

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
