Question

Determine if the lines that pass through the given points are parallel, perpendicular or neither. Line A: (-8, 8) and (-5, 10) Line B: (-7, 12) and (-5. 15)

Answer 1

Find the slopes using the following formula
\(\large slope=\LARGE\frac{y_2-y_1}{x_2-x_1}\).
If the slopes are equal then the lines are parallel.
If the product of the slopes is equal to -1 then they are perpendicular.
