12 1/4 because the original answer is 12 3/12 but you should simplify it to 12 1/4.
Plug the value of 9 in for y
9=-3x+6
Subtract 6 from both sides
3=-3x
Divide both sides by -3
-1=x
Final answer: x=–1
<span>Points (1, 1), and (2, 2) are on a line which has a slope of 1
ok?
The only point that lies on this line is (3,3).

Before we do anything we must convert radians to degrees using a table. pi/3 radians equals 60 degrees, meaning the central angle of this arc is 60 degrees. This also tells us that the length of the arc is 1/6 of the whole circumference. All we have to do now is calculate the circumference which is diameter x pi.
arc = 1/6 pi x 36
arc = 6pi cm
It would hafta be answer choice D
