Y = -1/2x + 6.....the slope is -1/2 and the y int = 6 or (0,6)
y - y1 = m(x - x1)
slope(m) = -1/2
(0,6)....x1 = 0 and y1 = 6
now we sub
y - 6 = -1/2(x - 0) <==
** You basically just label ur variables and sub them into the point slope form
Since that angle all together is 180, 100 is 2z-10 and z is 55
Step 1. convert percent to decimal form -- 20%=0.20
step 2. multiply percent decimal form to whole value -- 0.20*59.00
step 3. ???
step 4. profit
