I want to make sure im using the form correctly.

What is the slope of the line given by 2x+20=4y

would it then be 4y=2x+20

b=20 (or would I multiply that by 4 since it's 4y?)

m=-2

so the y-intercept would be either be 0,20 or 0,80 if I'm doing this correctly and the slope would be -2/1? I'm confusing myself the more I type so I'm gonna stop now

This is a tough subject for me and as I've stated earlier I don't have much help from a teacher since I'm taking this subject in Independent Study and this book sucks for explanations. Any help would be appreciated =)

Thanks
