Answer:
The slope of a line that is perpendicular to the given line is 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.
Solve for "y" from the equation of the line
:

You can observe that the slope of this line is:

By definition, the slopes of perpendicular lines are negative reciprocal, then, the slope of a line that is perpendicular to the give line, is

Well if FG is 4x and GH is 2x the you add them to get 6x for FH. Solve for x so 6x=18 which means x=3. Hope this helps
Answer: 26.47%
Step-by-step explanation:
Given the following :
markup based on cost = 36%
Assume a cost of $50
$50 × 1.36 = $68
Now, markup based on the selling price ;
$68 - $50 = $18
Therefore, ratio of cost price to selling price :
18 / 68 = 26.47%
