What is a necessary step for constructing perpendicular lines through a point on a line?

draw a line that intersects the first line at an acute angle using a straightedge.

draw a ray that intersects the first line at an acute angle using a straightedge.

draw arcs on either side of a given point on the line.

draw arcs on either side of a given point off the line

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

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.
