You might want to check with someone else, but I think all you do is plug 0 to x. If your y equal to 0, then yes, the line passes on point 0,0. Again, I'm not 100 positive if that is correct..
so i have a slop of -1/2...and i need to know if this line passes through (0,0) i know it seems really easy but just wondering...
do i need to know what b (in the formula y=mx+b) is equal to?
could someone please show me how to do this?
