Your answer would be A. y = -3 + 4
the line intercepts the y axis at +4
and the line decreases 3 units down and one unit to the right which makes the slope ( rise over run) -3/1 but you would just say -3
Surprisingly, a one-step equation <em>is </em>that simple; it's just an equation that takes one step to solve. So yes, 3 + 4 = 7 would be one you could do. You could also do a simple multiplication or division problem if you'd like, for instance you could do 4*3=12, or 12/4=3. Hope I helped!
x = 0.6x + 384
subtract .6x from each side
.4x = 384
divide both sides by .4
x = 960
