Answer:
y=13/3x-1
Step-by-step explanation:
k=(y2-y1) /(x2-x1)
A(0,-1) x1=0,y1=-1
B(3,12) x2=3, y2=12
k=(12-(-1))/(3-0)
k=(12+1)/3
k=13/3
y-y1=k(x-x1)
y-(-1)=13/3(x-0)
y+1=13/3*x
y=13/3*x-1

Trial and error on this one try each pair till you find negative slopes
C and D
Answer:
(3x+2y)(x+3y)
Step-by-step explanation:
First:
(3x²+ 2xy) + (9xy + 6y²)
then:
x(3x+2y) + 3y (3x+2y)
s0:
(3x+2y)(x+3y)
