Answer:
Perpendicular
Step-by-step explanation:
Let's start by finding the slopes of both lines.
Line A's slope is 3 (this is given).
We can determine line B's slope with the two points given. The slope formula is [tex]m=\frac{y1-y2}{x1-x2}[/tex]. Substitute in the values:
[tex]m=\frac{1-(-1)}{-3-3}[/tex]
and simplify:
[tex]m=\frac{2}{-6}[/tex]
So the slope of line A is -1/3.
-1/3 and 3 multiply to -1, so this indicates that the two lines are perpendicular.
