Brynn Whitney · Answer 1

X+y=-2

multiply the whole equation with 3

you will get 3x+3y=-6

x+y=-2

and 3x+3y=-6 are equivalent

the values of x and y is same in both the equations

so they define the same line.

Deon Blankenship · Answer 2

They define the same line because all of the numbers in the equation are tripled (properties of equality).
