You can't deduce the length of a side from the perimeters of a rectangle.
Say that
and
are, respectively, the short and long side of the rectangle.
So, we know that

But we can't solve exactly for
nor for
, unless more information is given.
Answer:
1) y = 3x+5
2) y = 
3) y = -x + 0
4) y = 
5) y = 
Step-by-step explanation:
y = mx+b
In slope-intercept form, these are important to know:
- y and x should stay as variables
- m = slope of the line
- b = y intercept
Using the facts above⬆, we can solve these problems
Remember: Substitute m and b using the given information
1) y = 3x+5
2) y = 
3) y = -x + 0
4) y = 
5) y = 
Hope this helps :)
Have a great day!
The data in the table are not proportionate because 4 pounds cost 3.55, meaning each pound costs 0.8875 while 6 pounds cost 4.33, which is 0.72166667 per pound.
