Here, it's already in slope intercept form (y = mx + b), in this case, the y-intercept is "b".
You can get the x-intercept by setting y = 0, and solving for x.

Well, if you understand the process then the answer will be clear. Are you understanding what I said? What is unclear?

No, that's incorrect. See here you have an equation in the form y = mx + b. Here, m and b are just numbers (constants). The important thing is that "m" is in front of the 'x' and b is by itself. In this form, the y-intercept is simply, b. So what is b?
