(x+y) / 2 =7
multiply both sides by 2
x+y=14


3x=.5y
divide both sides by .5
6x=y
 
plug 6x in for y 

x+(6x)=14
simplify
7x=14
divide both sides by 7 
x=2

Which of the following equations best represents the relationship in the table?
vazorg [7]

y= mx + b

when x is 0, y is 2 which you make the y intercept (b) 2

going from x=0 to x=1, the y coordinate moves down 4, so the slope would be -4
