Answer: -1/2
You get y = 2x - 5, so the slope is 2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is -1/2.
The value of x is: 
<u><em>Recall</em></u>:
Perimeter of a shape is the sum of all its sides
<em>Thus</em>:
Perimeter of the triangle = 
Perimeter of the rectangle = 
We are told that the perimeter of both shapes are equal. Set both perimeters equal and solve for x.
