Slope-intercept form gives is 
where 
is the slope of the line and 
is the y-intercept.
You can see that in slope-intercept form the
term is alone. In order to convert 
into slope intercept form, you must isolate the y term.
First we'll subtract 9x from each side.
Now we can divide both sides by -7.
Now we can simplify it.
