hoblos · Answer

is there options to choose from?

anonymous · Answer

x – 2y = –6
x – 2y = 6 
   x + 2y = –6
x + 2y = 6 
   x – 2y = –3
3x + 2y = 6 
   3x – 6y = 6
3x + 6y = –3

anonymous · Answer

A.x – 2y = –6
x – 2y = 6 
  B. x + 2y = –6
x + 2y = 6 
  C. x – 2y = –3
3x + 2y = 6 
  D. 3x – 6y = 6
3x + 6y = –3

i dont understand these problems any help is appreciated

hoblos · Answer

mm it is A

phi · Answer

You know the equation of a line in standard form?

phi · Answer

The top line is the same as y= x/2 +3 or 2y = x +6 or -x + 2y=6

phi · Answer

or (because I don't see any -x in your answers) x - 2y = -6
(by mult both sides by -1)

hoblos · Answer

from the graph you can calculate the slope and you can use any point from the graph to find the equation

phi · Answer

The bottom line has the same slope, but a y-intercept of -3
