Is the answer, you have to get all you terms that being x+6+12x-7
6-7=-1
X+12x=13x
Put them together with the Xs first

Answer:
All except 4th and last.
Step-by-step explanation:
The one that says equation is definitely wrong because it doesn't have an equal sign anywhere (there is nothing to solve there).
The one that says 5 plus x^2 that means 5+x^2 instead of 5x^2.
They should have said 5 times x^2 there which actually means 5x^2.
So I don't like the way some of these are written but the only two that are really wrong are the 4th one and the last one.
Answer:
y=x+9 (or y=1x+9, same thing)
Step-by-step explanation:
The equation for Slope-Intercept is y=mx+b. M is the slope, an B is the Y-intercept. Since 1 is the slope, m=1, and B=9 because 9 is the Y-intercept.
