Answer:
See below. 
Step-by-step explanation:
So we started off with the equation: 

And we subtracted x from both sides to acquire: 

Now, this is essentially slope-intercept form. Recall that the slope-intercept form is: 

Where m is the slope and b is the y-intercept. 
If we rearrange our equation: 

And put some parentheses: 

We can see that this is indeed slope-intercept form. 
And we can see that m is -1 and b is 2. 
In other words, the slope is -1 and the y-intercept is 2.
