√(y2-y1)²+(x2-x1))
Simple Pythagorean Theorem.....
√(12)²+(5²))
√(169)
B.) 13
Perpendicular lines intersect to form a right angle
So we can eliminate A
Parallel lines never intersect
So we can eliminate B
Intersecting lines CAN have 2 or more points but DO NOT always have 2 or more, meaning they can sometimes only intersect at one point.
So we can eliminate C
And as previously stated, parallel lines never intersect, which confirms what option J states.
So your answer is J

= -8(12 - 4)
= -8(8)
= -64
