Given, y varies directly as x
So,
Where c is a constant
When y equals 5 when x is 8
So,
So, the relation between y and x
now , when x = 9
Substitute with x to find y
So, the answer is option 2. y = 45/8

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:
