# 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 ?

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., ${m}_{l} = \frac{4}{5}$; in this way every point of $m$ is "reflected" about the x-axis.
