If you rearrange x - y = 2 into slope-intercept form,
x - y = 2
+ y
x = 2 + y
- x
0 = 2 + y - x
- 2
-2 = y - x
+ x
y = -2 + x
you get y = -2 + x, which means that the y-intercept is -2. I hope this helps!

You have to multiply -2 to all of the numbers inside the parenthesis and you will have your answer. -6v+4x+2
Answer:
3x² – 2x – 8
=> 3x² – 6x + 4x – 8
=> 3x( x – 2 ) + 4( x – 2 )
=> ( 3x + 4 ) ( x – 2 )
Therefore,
Either, 3x + 4 = 0
3x = - 4
x = - 4/3 (Ans)
And,
x – 2 = 0
x = 2 (Ans)
