Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b
Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14
Finally, put in everything we've found to finish the equation.
y= -3x+14

Answer:
As the number of sides increases, the measures of the angles increase
see the explanation
Step-by-step explanation:
we know that
The measure of the interior angle in a regular polygon is equal to

where
n is the number of sides of the regular polygon
x is the measure of the interior angle in a regular polygon
we have that
<u><em>Examples</em></u>
<em>A triangle</em>
n=3 sides

<em>A square</em>
n=4 sides

<em>A pentagon</em>
n=5 sides

<em>A hexagon</em>
n=6 sides

so
n ----> 3,4,5,6...
x ----> 60°,90°,108°,120°,...
As the number of sides increases, the measures of the angles increase
The pattern is 
Answer: width is 9 , 13×8=104, 936/104=9
Check it 13×8×9=936
