Answer:
a
Step-by-step explanation:
The equation of a proportional relationship is
y = kx ← k is the constant of proportionality
Divide both sides by x
= k
To find k use any ordered pair from the table
Using (2, 
) , then
k = 
= 2 × 
= 
y=1/3x-1
We know straight away that the y intercept is -1 from the equation.
y-intercept: (0,-1)
To find the x intercept plug in 0 for y in the equation.
y=1/3x-1
0=1/3x-1
1/3x=1
x=3
x-intercept: (3,0)
answers: y-intercept: (0,-1) and x-intercept: (3,0)
Answer:
The slinky situation
Step-by-step explanation:
To make a rate, divide one value by the other.
For the short bungee,
6 inches ÷ 3 pound = 2 inches per pound
While the slinky,
36 inches (remember to convert feet to inches) ÷ 1 pound = 36 inches per pound
As you can tell by the numbers, 36 inches per pound is way better than the 2 inches per pound.
Divide both length and width by the dialtion factor and that will be the dimensions of the new rectangle. 2.5714in by 3.4286in. Round as needed
