Question

In the coordinate plane, line "m" is the reflection of line "l" about the x axis. If the slope of line "m" is - 4/5 what is the slope of line ?

Answer 1

Look I may be wrong on this one but I think that the slope of line `l` will be the same but with opposite sign, i.e., `m_l=4/5`; in this way every point of `m` is "reflected" about the x-axis.
