195/8 : 13/4
= 195/8 x 4/14
= 780/112
= 6 108/112
= 6 54/56
= 6 27/28
The answer is 43 i think hope it helped
For this case we have that by definition, the equation of a line in the point-slope form is given by:

Where:
m: It is the slope of the line and
is a point through which the line passes.
We have the following equation of the slope-intersection form:

Where the slope is 
By definition, if two lines are perpendicular then the product of their slopes is -1.
Thus, a perpendicular line will have a slope:

Thus, the equation will be of the form:

Finally we substitute the given point and we have:

Answer:
Option B
2u+7u=9u
9u=81
Divide both sides
U=9
