Which graph
or equation represents a nonproportional relationship?

The equation that represents a proportional relationship must have this form:

And the graph of a proportional relationship must be a a line that passes thorugh the origin.

Step-by-step explanation:

Since the graph is not attached, I will give you a general explanation about how to solve the exercise.

The equation of a line that passes through  the origin is the following:

Where "m" is the slope of the line.

The proportional relationships have the following form:

Where "k" is the Constant of proportionality.

Therefore, the graph of proportional relationships is a line that passes through the origin.

Therefore the equation that represents a proportional relationship must have this form:

And the graph is a a line that passes thorugh the point

so then what are you asking?

step-by-step explanation:

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
