Answer:

perpendicular

Explanation:

Two lines are perpendicular if their slopes are negative reciprocals.

we need to find the slopes of both lines.

for QR, Q(-6, 11) and R(2, -1)


m=(y2-y1)/(x2-x1)

the slope of QR is -3/2.

for ST, S(-4, 8) and T(-1, 10)


m=(y2-y1)/(x2-x1)

the slope of ST is 2/3.

-3/2 is the negative reciprocal of 2/3

QR and ST are perpendicular
