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.
Definitely Graph C.
The dots are aligned correctly to the line better than the other graphs.
Never true. Vertical angles are equal to each other, not adjacent to each other.
62 +510 + 10 = 572
572 ÷ 2 = 286.
6+8=14. 6+8+11=25
so 14 out of 25 is the answer
