Answer:
Y=3x-4
Step-by-step explanation:
The equation would be y+y1=slope(x+x1) which means it will be y+-21=slope(x+7)
I believe that is right. I don't know what the slope is though. Welp.
Answer:
its 134
Step-by-step explanation:
If one square takes 16.4 cm of wire, this means that to form 25 identical squares you need 25(16.4) cm of wire = 410 cm
To convert this to m you just need to divide it by 100 because there are 100 cm in one meter = 4.1 m
Therefore your final answer is: You need 4.1 m of wire to form 25 squares, each with a perimeter of 16.4 cm.
