Karla uses a compass and straightedge to construct perpendicular lines daryl uses technology to construct perpendicular lines describe how karlas construction steps will be different than daryls>

Karla uses a traditional, manual method of constructing perpendicular lines, using a straightedge while Daryl uses a latest drawing tools to draw them.

Both the methods are correct, however the amount of effort and time taken will vary for these two different methods.

Since Karla is constructing perpendiculars manually so she has to go through all the methods carefully, from placing the straightedge to marking the arcs and joining them correctly. It will take her a little longer and more effort to get the accurate results.

On the contrary, the drawing tool used by Daryl will be much more efficient as he can construct perpendicular lines just by specifying a point in no time.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
