When a line passes through the two points
, its slope is given by the formula 
In this question, a line L passes through the points 
So, its slope is given by

When two lines are perpendicular, then the product of their slopes is -1.
Since, the slope of the line L is
, so the slope of the line which is perpendicular to the given line L is
as the product of
.
D) 34/5 because 6(5) = 30 30+4=34 , so its 34/5
12) 12, 8
12 - 8 = 4
12 + 8 = 20
Answer: 4 < x <span>< 20
13) 11, 3
