Answer:

#(3,color(red)(a)) = (3,color(red)(5/3))#
and #(color(blue)(b),-1)=(color(blue)(1),-1)#

Explanation:

Given #4x-3y=7#

Point 1
If #(x,y) = (3,a)#
#color(white)("XXX")4(3)-3(a)=7#

#color(white)("XXX")rarr 12-3a=7#

#color(white)("XXX")rarr -3a= -5#

#color(white)("XXX")rarr a = 5/3#

Point 2
if #(x,y)= (b,-1)#
#color(white)("XXX")4(b)-3(-1)=7#

#color(white)("XXX")rarr 4b+3=7#

#color(white)("XXX")rarr 4b=4#

#color(white)("XXX")rarr b=1#
