You need it in "slope and intercept" form. Slope and intercept form is:
Y = (slope) X + (intercept)
The equation you have ALMOST looks like the form you need, but there's something wrong.
What you have is: Y + 1 = X . What you need is ' Y ' on one side all by itself.
How can you get rid of that " + 1 " that's on the left side with Y ?
Well, you can subtract ' 1 ' from the left side of the equation. But whatever you do to one side, you must do the same thing to the other side. No problem ! Take the original equation:
Y + 1 = X
Subtract ' 1 ' from each side:
Y = X - 1
And there you have what you need.
Remember, "slope and intercept form" is
Y = (slope) X + (intercept) .
and you have
Y = (1) X + (-1)
The slope is 1 . The intercept is -1 .
You're letting something easy scare you and grab you by the throat. Don't let it do that.
