Step-by-step explanation:

The complete questions in the attached figure

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

Part 5) The number of pounds in a bag of flour varies directly with the number of ounces. Write a direct variation equation  that describes the relationship. Use your equation to  determine the number of pounds in 152 ounces.

Part a) Write a direct variation equation  that describes the relationship

Let

x ------> number of ounces

y ----> number of pounds

Observing the graph we have

The point (16,1)

so

Fin the value of the constant of proportionality k

substitute the values

The equation of the direct variation is

Part b) Use your equation to  determine the number of pounds in 152 ounces

we have

For

substitute the value of x in the equation and solve for y

Part 6) The number of pencils for sale varies directly with the  number of boxes. Write a direct variation equation that  describes the relationship. Use your equation to  determine the number of pencils in 14 boxes.

Part a) Write a direct variation equation  that describes the relationship

Let

x ------> number of boxes

y ----> number of pencils

Observing the graph we have

The point (1,50)

so

Fin the value of the constant of proportionality k

substitute the values

The equation of the direct variation is

Part b) Use your equation to  determine the number of pencils in 14 boxes.

we have

For

substitute the value of x in the equation and solve for y

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
