Question

Ship A receives a distress signal from the southwest, and ship B receives a distress signal from the same vessel from the north. At what location is the vessel in distress located? Describe how you arrived at your conclusion using complete sentences. Which theorem or postulate does this demonstrate? You must show all work and steps in order to receive credit.

Answer 1

What are the two formulas for the ships?

Answer 2

This all the question gives me that's why I'm confused

Answer 3

Ok we need to give the two ships formulas that reflect there slope and relation ship to the (x,y) coordinates. Let's look at ship B. What formula can we assign to it?

Answer 4

What do u mean formula

Answer 5

What is x always going to be for ship B?

Answer 6

1???

Answer 7

Correct. When a line on the graph is parallel to the y axis it will always be x= (some value). So we know the Ship B has a formula for its line of X=1.

Now ship A. Can you tell me what the slope would be for this line?

Answer 8

-1

Answer 9

Actually it is positive 1. Remember a slope is based on the way it runs not so much the direction. Given the slope is 1. Can you come up with the linear equation for ship A?

Answer 10

I can't remember what it is I'm in geometry and barely remember stuff from algebra 1

Answer 11

(y-y2) = M(slope(x-x2). (x2,y2) represent the points on the graph. Use this to get the formula

Answer 12

Ok

Answer 13

Would it be x+3+y-4=1 it doesn't seem right though

Answer 14

(y-4) = 1(x-3) Do you see this?

Answer 15

Yea I got that when I distributed

Answer 16

So you need to make it in the following formula y = x +?. So make y-4=x-3 into y = what

Answer 17

x+1

Answer 18

Great job. So our equation for ship A is y=x+1. And for ship B it is X=1. So what do you think the point will be where Ship A and Ship B signals cross?

Answer 19

(1,2)???

Answer 20

Winner winner chicken dinner..Great Job!!!!

Answer 21

Lol thanks..... so would this be the intersecting lines postulate

Answer 22

So when writing your description you would say I need to determine the formula for the the lines of the two ships signal and determine where they intersect.

Answer 23

You got it!!!!

Answer 24

Ok thank you for the help
