Need help on number 8

Answer for the first box:  y = 0

Answer for the second box: y = x+1

Explanation:

The line y = 0 is the horizontal line that overlaps the x axis perfectly. If the line of reflection is y = 0, then you reflect over the x axis to have F = (6,3) move to F' = (6,-3). The perpendicular bisector of FF' is y = 0, which is exactly the line of reflection. Point E is on the line y = 0.

Now create any line you want that does not go through point E. One such line is y = x+1. This line of reflection will play the role as the perpendicular bisector of FF'. Point E is not on the line because plugging x = 0 does not lead to y = 0, and instead it leads to y = 1.

So as you can see, Kari's claim is not 100% correct as there are counter-examples to show it doesn't always work.

F(y) = 3y + 5x+5x this keeps F perpendicular.

F(x) = 10x +3y

When E stays constant (0,0) and F stays constant (0,10)

when f = 10

Then the lines are perpendicular

We can rephrase this as When EFF = (0,0) (0,10) (5,3) changes to EFF  (0,0) (0,10) (10,3) then FF becomes perpendicular with FE.

Step-by-step explanation:

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.
