Step-by-step explanation:

1. slope=-3/2-3 is at the top,2 is at the bottom

y intercept=4-The y intercepts or goes past at 4,

equation=y=-3/2+4-We put it all together and we get y=-3/2+4!

2. slope=-3/2-It starts at 3 again,and ends at two again.

y intercept=0-The y touches the line at 0,or the middle

equation=y=-3/2-y equals the slope and we subtract y.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

1/3 + 1/5 = 8/15.
