Suppose you were stranded on a desert island with only a convex lens and a mirror. Describe how you could use each of these tools to signal for help.

Explanation:

You could use the convex lens to create a fire by lining it up with the sun and pointing it at some type of dry plant. Same thing with the mirror. You could also use the mirror to get the attention of people who pass by or fly over.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
