Answer:
y=-x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-1)/(5-3)
m=-2/2
m=-1
y-y1=m(x-x1)
y-1=-1(x-3)
y-1=-x+3
y=-x+3+1
y=-x+4
the answer is true. if you have square with 4 cm on all sides and double it, it will become 8 cm on all sides. the first square has a perimeter of 16 and the second square has a perimeter of 32. therefore the perimeter doubles.
