I need help too but nobody will help me at all
We have that
<span>the function of the line is
3x-3y=9
clear y
3x-9=3y
y=(3x-9)/3
y=x-3
for x=2
y=x-3----->y=2-3------> y=-1
the point is (2,-1)
the answer is
the y coordinate is -1</span>
9÷2 is 4.5
k > 4.5
now just simply observing in above we can find this condition is fulfilled in third one
3(5b+1)(5b-1)
hope it helps
