Have Ze gud evening.
Ffed is a undercover name lol.
The answers are RBR and BBR
Trust me I took the test
9 is x -6 is y and -2/3 is the slope so you do
y=mx+b
-6=-2/3x9+b
y= -2/3x
Make y the subject:
2x+y=-5
2x+5=-y
y=-2x-5
y=-2x+2 is the answer as the slope does not change but the y intercept does

Correction:
1⟩
Given equation is x²-3x = 4
⇛ x²-3x -4 = 0
⇛ x²+x-4x-4 = 0
⇛ x(x+1)-4(x+1) = 0
⇛ (x+1)(x-4) = 0
⇛ x+1 = 0 or x-4 = 0
⇛ x = -1 or x = 4
2.⟩
Given equation is x²+4x+4 = 0
⇛ x²+2x+2x+4 = 0
⇛ x(x+2)+2(x+2) = 0
⇛ (x+2)(x+2) = 0
⇛ x+2 = 0
⇛ x = -2
