Answer:
Isolate Y and X? I am not sure if there is a full question for this but I think this is what you meant.
Step-by-step explanation:
We can solve for either:
y = -2x+7
y - 7 = -2x
y - 7 / -2 = x
That's x.
If you were asking for the slope intercept: y = mx + b
m = slope
negative opposite direction
etc.
