Answer:
The one on the bottom left.
Step-by-step explanation:
The graph of a proportional relationship is a line that goes up at a constant rate and goes through the origin.
Since it is connected to the origin it's proportional
notice how none of the others are connected to the origin
It needs to be a straight line
So, x and y have a proportional relationship.
The form of the equation of a proportional relation is y = kx, where k is the constant of proportionality.
A graph of a proportional relationship is a straight line that passes through the origin.
The constant of a proportionality in a graph of a proportional relationship is the constant ratio of y to x (the slope of the line).

One-half a number (x) is equal to 14.
One-half: 1/2
a number x: multiplied by x
is equal to: =
1/2x = 14
If you were going to solve for it, divide both sides by 1/2.
x = 28
Answer:

21 inches
A^2+b^2. =C^2
A^2+ 20^2=29^2
Sqrt A + 400= 841
Sqrt A = 841-400
Sqrt A= sqrt 441
A= 21
