The product of the slopes is -1.
The rate of this would be 11 sit ups because 55 divided by 5 would give you the answer 11
The constant is 15, divide 45 by 3 then you’ll get 15. multiply 15 with the minutes and you’ll get the sit-ups
Suppose, we are given
two points as
F as (x1, y1)
H as (x2, y2)
assume it divides in m/n
we can use formula

now, we are given points as
F=(x1, y1)=(4,8)

H=(x2, y2)=(10,12)


so,

now, we can find


so, point is
