i have a question about straight line graphs.
what does it mean when the line passes through the origin?
what does it mean when it doesnt?
many thanks
hi
well,when a line passes through the origin ( which is the couple $\displaystyle (0,0) $) the $\displaystyle y$ intercept will equal zero.and hence any line that passes through the origin will have the equation $\displaystyle y=mx $.

Almost true. The line x= 0 passes through the origin but does not have that form.
