I think the answer is B The region shaded below a solid boundary line. I'm only 75% sure
they are saying x = 3 so you would use the middle equation
so -4x becomes -4(3)
-4 * 3 =-12
for 6
in a
given
slope(m)=1
point=(2,-4)=(x1,y1)
we know
equation of straight line
y-y1=m(x-x1)
y+4=1(x-2)
y+4=x-2
therefore x-y-6=0 is the required equation
substituting with ax+by+c=0 we get
a=1
b= -1
c= -6
