Answer:
K(-4,8) is the ortho center.
Step-by-step explanation:
In a right angled triangle, The vertex of the right angle is the ortho center.
Here we are given
J(-4,-1), K(-4,8) & L(2,8)
Using distance formula we get



So we can say that

By converse of pythagorean theorem we get

Hence the Vertex of the right angle is K(-4,8)
K(-4,8) is the ortho center.
30 + 2 = 32

Assign x as the number of females.
Since makes are six times more: 6x is the male variable.
In total there are 7x students.
So the fraction for males is : 6/7
There's no way to simplify further because there's no term common to both the denominator/numerator.
Answer: 6/7
