Answer: Prependicular
Step-by-step explanation:
Since you have 2 points of a line you can find the gradient of each line using (y2-y1)/(x2-x1) or change in y divided by change in x. For line one this is (-3-5)/(-1+7) = -8/6 = -4/3
For line two this is (-1-3)/(3-0) = -4/3
Since they have the same gradients they are in fact parallel
Perpendicular lines will have the negative recpriocal of each other gradient.
