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.
(5-12)^2+8/(-2)
(-7)^2+8/(-2)
(49)+8/(-2)
(49)+(-4)
45
Using PEMDAS, your answer would be 45.
