Use the drawing tool to modify the model, showing the direction of prevailing winds in the Northern hemisphere and convection currents. Label hot and cold air on your convection currents.

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

it takes about 30 days for it to break down

show the wavelengths of a wave. show the crests of a wave.

i would say
