Hello,

If the slope is 0, then the line ishorizontal, that is to say : any point on this line has a fixedordinate(here, it's 1)

This only holds true when the line isB.) (2,1) and m is undefinedvertical, that is to say : any point on this line has a fixedabscissa

This can be written x=2/5Find the slope and the y-intercept of the equation of the line algebraically

A.) 5x-2 equals 0

Refer to question B.)
