8. The y-intercept is -10. You can find this by just seeing where the line would hit the y-axis. This is basically the starting point so the Scuba Diver's decent started at -10m.
9. You have the y-intercept so put that in slope-intercept form. y=mx+b
y=mx - 10
Now find the slope by picking two points and using the slope formula. I'll use
(30,-6) and (50,-4), and then plug in the values. 30 = x1, -6 = x2, 50 = x2, -4 = -4. Simplify.
m= y2-y1 -4 - (-6) 2 1
-------- = ----------- = --- / 2 = ---
x2-x1 50 - 30 20 10
Answer:$440
Step-by-step explanation:
Principal(p)=$200
Rate(r)=12%
Time(t)=10years
Simple interest=(pxrxt) ➗ 100
Simple interest =(200x12x10) ➗ 100
Simple interest=24000 ➗ 100
Simple interest=240
Total amount=p + simple interest
Total amount =200+240
Total amount =440

Answer:
Option 1
Step-by-step explanation:
First we need to analyse the question to figure out what we need to do. The question is saying that a line is parallel to the y-axis. We know that the y-axis goes up and down, meaning that our line should be pointing up and down crossing the point (2,-7). In order to find where the line is placed, we would have to look at the x-axis to figure out where it is. Using the info provided we could see that the line has to pass (2,-7), and the x for that point is 2. Using all the info we have concluded we know that the equation of the line is x=2.
