#(-4, 1)# does not lie on the given line.

#(-4,1)# represent #x and y# values .

Substitute the #x-# value into the equation and check whether that makes the equation true.

#y = -5/4x-2#

#y= -5/4(-4) -2#

#y = 5-2#

#y=3#

This is not equal to the given y-value of 1 which means the point
#(-4,1)# does not lie on the given line.
