Slope of AB
m = (y2 - y1)/(x2 - x1)
m = (11 - (-4))/(2 - (-1))
m = (11 + 4)/(2 + 1)
m = 15/3
m = 5
The slope of line AB is 5
Slope of CD
m = (y2 - y1)/(x2 - x1)
m = (10 - 1)/(4 - 1)
m = 9/3
m = 3
The slope of CD is 3
Since the two slopes are not equal, this means the lines are not parallel.
Since (slope of AB)*(slope of CD) = 5*3 = 15 is not equal to -1, this means the lines are not perpendicular
Answer: Neither (not parallel; not perpendicular)
Gcf is the greatest common factor. THe gcf of 98 and 42 is 14

Answer:
$500
Step-by-step explanation:
5,000-2,500=2,500
20% of 2,500 is 500 so the amount that he owes is $500
Hope it helps :)
