Which graph represents a proportional relationship?

The first graph represents a proportional relationship

Step-by-step explanation:

In a proportional relationship two quantities vary directly with each other. That means that variable y varies directly as x.

So,  in this case ,  we have 4 situation.  

In the first situation ,  y increase directly as x.  

In the second ,  we have a exponential relationship ( y increase faster than x)

The 3rd and 4th situation is the same,   y don´t varies directly as x

a: 1/6, j: 1/4

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
