Answer: 
Step-by-step explanation:
1. By definition, if 
when 
, then:
2. Keeping this on mind, to find the value of 
when 
, you must apply the following proccedure:
3. Now, you must solve for , as following:
4. Then, the result is:
AB = AC
18 = 3x + 6
-6 -6
18-6 = 3x
12/3 = 3x/3
4 = x
Answer:
The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!
hope this helped!
