The slope of the given line is m = (19-11)/(5-3) = 8/2 = 4

the perpendicular line has slope (-1/4)

Since you said either point, I'll pick (3,11)

B = y - mx = 11 - (-1/4)(3)

= 11 + 3/4

47/4

y = (-1/4)x + 47/4

now , IF you choose (5,19) then the

equation is

B = y - mx = 19 - (-1/4)(5)

= 19 + 5/4

= 81/4

y = (-1/4)x + 81/4

Note that (5,19) does not work in the first equation because it is not on it...

Note that (3,11) does not work in the second equation because it is not on it....
