Line m passes through points (3, 15) and (10,9). Line n passes through points (2,9) and (9, 3). Are line m and line n parallel p
erpendicular?
1 answer:
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.

x^2 - 6x - 27
(x - 9)(x+3)
Answer:
x=8
Step-by-step explanation:
5(x-7)=75
5x-35=75
