To rotate the figure 180 degrees, you would make it so all the points are:

(x,y) to (-x,-y)

Basically, you would switch every sign on the point.

(1,-1) -> (-1,1)

(3,-2) -> (-3,2)

(3,-4) -> (-3,4)

Those new points would be P'Q'R'.

Then when you reflect over the x-axis, you would flip every y sign.

(-1,1) -> (-1,-1)

(-3,2) -> (-3,-2)

(3,-4) -> (3,4)

You would chart those points as P"Q" R".

I hope this helps! (review my answers)

Sorry this took so long!

Segment AB has point A located at (4, 2). If the distance from A to B is 3 units, which of the following could be used to calcul

miv72 [106K]

Applying the distance formula, to calculate the coordinates of B, use: 3 =√[(x-4)² + (y-2)²]

<h3>What is the Distance Formula?</h3>

The distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , is used to find the distance between two points on a coordinate plane.
