G is the center of gravity of a triangle ABC and A ′ is the midpoint of BC and L is the center of gravity of (A, −1), (B, 2), and (C, 2).
1. Show that 4LA ′ = LA. Solve for L
2. Prove that L and G are symmetric relative to A'.

answer: i think it's a

step-by-step explanation:

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
