Answer:
Is there a graph to see how it looks.
We can rearrange the initial equation to y=mx+b
y=2x-5
Since perpendicular slopes must equal -1,
x=the perpendicular slope
2x=-1
x=-1/2
(Or you can just take the negative reciprocal above is just the "formula form" for it)
Therefore, the perpendicular slope is -1/2

72 inches.
<span>72/6=12inch sixths </span>
<span>each sixth is cut into a third </span>
<span>12/3=4 inches </span>
<span>each of these eighteenths (6*3=18) have a length of four inches. </span>
<span>Check. 18*4 should equal 72. You have 18 pieces, each four inches long.
Got it all?</span>
