Determine if Line AB and Line CD are parallel, perpendicular, or neither. Show work.
(Take care to copy problems correctly.)
1. A(1,5), B(4,4), C(9, -10), D(-6, -5)
2. A(-6, -9), B(8, 19), C(0, -4), D(2,0)
The full answer is so long. I’m too lazy to do it but i can tell u how. First write the equation of line AB then equation of line CD then compare the slope of both line AB and CD.
