Answer: they are parallel

Step-by-step explanation:

find slope of line m:

Use y2-y1/x2-x1

your m equation --> 9-15/10-3 which makes the slope of m = -6/7

find slope of line n:

Use y2-y1/x2-x1

your n equation --> 3-9/9-2 which makes the slope of n = -6/7

The slopes are the same, therefore line m and line n are parallel.
