so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)
(7-(-2))/(0-8)
simplify
9/-8
simplify -9/8
now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.
y=mx+b
-2=(-9/8)(8)+b
multiply (-9/8) by 8 to get -9
-2=-9+b
add 9 to both sides
7=b
so our equation is now
y=-(9/8)x+7
Cut the three lines off center enough so that when they intersect they form a seventh piece in the center of the circle. I hope this is clear enough. If it's not, tell me and I'll try to elaborate further.
Answer: a = -8
3(2x - a) = 2(3x + 12)
⇔ 6x - 3a = 6x + 24
⇔ - 3a = 24
⇔ a = -8
