Michael worked 4.5 hours. 65.75 - 36.50 = 29.25, therefore, Michael made $29.25 not including tips. 29.25/6.50 = 4.5
20/5
4x/x adding 10 to each
4x+10/x+10 =2
Multiple x+10 to each side
4x+10=2x+20
Then subtract and get
2x=10
Divide
X=5
Now plug it back in
20/5
Answer:

CD slope: y = 6/9x - 6
Once the slopes are simplified:
AB: -3/2
CD: 2/3
