Answer:

y-6= -2(x+2)

Step-by-step explanation:

A= (-2, 6)

B= (2, -2)

y= mx+b

slope:

m= (y2-y2)/(x2-x1)= (-2-6)/(2+2)= -8/4= -2

intercept:

6= (-2)*(-2)+b ⇒ b= 6-4= 2

the function is:

y= -2x+2

y-2=2(x+2) ⇒ y= 2x+6 - no

y-6= -2(x+2) ⇒ y= -2x +2 - yes

y-2= -2(x+6) ⇒ y= -2x - 10- no

y-2= -2(x+2) ⇒ y= -2x- 2 - no
