Which equation is an identity?
3w + 8 – w = 4w – 2(w – 4)
7m – 5 = 8m + 7 – m
–3y + 3 = –3y – 6
9 – (2v + 3) = –2v – 6

  3w + 8 – w = 4w – 2(w – 4)

Step-by-step explanation:

The simplified forms of each of these equations are ...

2w +8 = 2w +8 . . . . . .the identity you're looking for7m -5 = 7m +7 . . . . . . never true-3y +3 = -3y -6 . . . . . . never true-2v +6 = -2v -6 . . . . . . never true

I’m pretty sure the slope would be 1 since the x and y values increase by 1
