When the equation of the line is given in such a form (y is explicitly expressed via x), the slope is the coefficient at x.
So, the slope is -5 in your problem.
To find y-intercept, simply put x= 0 in the equation of the line.
You will get then for y-intercept the value of -1.
This problem is not "to think".
It is to test if you know the definitions.
