Help will. Give show work

so first you have too make both of the denominators the same and we know that 4 can become 8 if you multiply it by 2 so you have to multiply it by both the numerator and denominator so

then equation is

7/8 + 2/8

then u have to add 7 + 2 which equals 9 then put it into a fraction so it 9/8 and then u have to make it a mix number which is 1 1/8

hope this helps sorry its super long

Step-by-step explanation:

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
