For this case, the first thing we must do is rewrite the lines.
 We have then:
 y = -2x + 5
 y = -2x + 6
 We observe that both lines have the same slope. That is to say,
 m = -2
 Therefore, the lines are parallel.
 Answer: 
 Parallel lines for having the same slope.

Math help please TY :3<br><br> HWAJDSK 10 POINTS REWARDING !!

I will do Point A carefully, The others I will indicate. Start with the Given Point A. Then do the translations

A(-1,2) Original Point

Reflection: about x axis:x stays the same; y becomes -y:Result(-1,-2)

T<-3,4>: x goes three left, y goes 4 up (-1 - 3, -2 + 4): Result(-4,2)

R90 CCW: Point (x,y) becomes (-y , x ) So (-4,2) becomes(-2, - 4): Result (-2, - 4)

B(4,2) Original Point

  • Reflection: (4, - 2)
  • T< (-3,4): (4-3,-2 + 4): (1 , 2)
  • R90 CCW: (-y,x) = (-2 , 1)

C(4, -5) Original Point

  • Reflection (4,5)
  • T<-3,4): (4 - 3, 5 + 4): (1,9)
  • R90, CCW (-9 , 1)

D(-1 , -5) Original Point

  • Reflection (-1,5)
  • T(<-3,4): (-1 - 3, 5 + 4): (-4,9)
  • R90, CCW ( - 9, - 4)

Note: CCW means Counter Clockwise

The graph on the left is the same one you have been given.

The graph on the right is the same figure after all the transformations

Mr. Bennett owns 4 restaurants. The mean number of tables is 30. Which number line shows what could happen to the mean if he buy
expeople1 [14]
Number of tables al four restaurants have;
= 4 * 30
=120 tables
Two new restaurants + 4
=6 restaurants
(120+15+9)= 144 tables
Mean = total # of tables/ total # of restaurants;
144/6
=24
This is the mean so it decreases. I hope this helps even though you didn’t actually post the number line
