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?
THANKS!
your question as asked makes no sense. slopes don't pass through anything. perhaps you wanted to know if a straight line with slope -1/2 passes through (0,0). in that case, it is easy. if the line has no y-intercept (that is, it's y-intercept is zero, there is no b in the equation of the line y = mx + b) then yes, it passes through the origin. so if you are talking about the line y = (-1/2)x, then the answer is yes. please be specific next time
