Find the roots of
-1/7(y-7)=(x+2)^2

(√7-y)/√7-2

-(√7-y)/√7-2

Step-by-step explanation:

-1/7(y-7)=(x+2)^2

(x+2)^2 =-1/7(y-7)

x+2=(√7-y)/√7 or x+2=-(√7-y)/√7

x₁=(√7-y)/√7-2 or x₂=-(√7-y)/√7-2

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

the infinity sign
