Determine whether line AB and line CD are parallel, perpendicular, or neither. A( 4, 2), B(-3, 1), C(6, 0), D(-10, 8)

Step-by-step explanation:

If AB an CD are parallel, then their slopes are the same.

If AB and CD are perpendicular, then the product of their slopes is equal -1.

The formula of a slope:

Calculate the both slope:

The line AB and line CD are not parallel

The line AB and line CD are not perpendicular.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
