Ineed with questions 20 through 25

20. we see that is has a yint of 1
it has a slope of 2/3
y=2/3x+1

21. has a yint of -1
has a sloe of -1
y=-x-1

22. from the center, go 3 units down and plot a point there
from that point, go 4 units up, and 1 unit to the right, put a point there
connect those 2 points wit a line

23. go 2 units up from center
go left and right forever (horizontal line going throug y=2 or (x,2)

24. graph the point (1,-3)
go 2 units up and  1 to right (-1,2) and plot a point, connect the points

25. y=-1/4(x-10)
graph the point (10,0)
go 1 down and 4 to the right (14,-1) and connect the points

use desmos graphing caluclator if yo ar stuck

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
