Find an equation of the line having the given slope and containing the given point. Express your answer in the form x=a,y=b or y=mx+b; with m=-8,(7,0)? how do I do this?

i go with y=mx+b. just plug in a point on the line, try to get a solid number, no decimals, and postive if possible. If not that's okay. Then plug in your slope and solve for b. So using (7,0) your equation should look kinda like this:

y=mx+b

0= -8(7)+b

....that doesn't seem right....

The best way to go about it, is to find your y-intercept, and plug that in for b. then plug your slope in for m.Find some point on your line, and plug it in. Sorry-I'm tired and feel kinda sick, so just try it out and see where it gets you. I'm sorry if you're still confused or don't get a good answer. Good luck.
