Which statement accurately describes how to reflect point a (−2, 1) over the x‐axis?
a. construct a line from a perpendicular to the x-axis, determine the distance from a to the x-axis along this perpendicular line, find a new point on the other side of the x-axis that is equidistant from the x-axis.
b. construct a line from a parallel to the x-axis, determine the distance from a to the x-axis along this parallel line, find a new point on the other side of the x-axis that is equidistant from the x-axis.
c. construct a line from a perpendicular to the y-axis, determine the distance from a to the y-axis along this perpendicular line, find a new point on the other side of the y-axis that is equidistant from the y-axis.
d. construct a line from a parallel to the y-axis, determine the distance from a to the y-axis along this parallel line, find a new point on the other side of the y-axis that is equidistant from the y-axis.

A. Construct a line from A perpendicular to the x-axis, determine the distance from A to the x-axis along this perpendicular line, find a new point on the other side of the x-axis that is equidistant from the x-axis.

Step-by-step explanation:

The rule for a reflection over the x -axis is (x,y)→(x,−y) . The given point is A(-2,1) .The reflected point will be A'( -2,-1) .

To locate the reflected point A' we draw a perpendicular line from A then we measure the distance from point A to x axis along the perpendicular line drawn .The reflected point A' is constructed on the other side which is equidistant from x axis as was point A.

Option A is the right option.

The Answer is

Step-by-step explanation:

A. Construct a line from A perpendicular to the x-axis, determine the distance from A to the x-axis along this perpendicular line, find a new point on the other side of the x-axis that is equidistant from the x-axis.

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
