Determine if the equation y = 2/5 x − 4 y=25x-4 represents a proportional relationship. If so, determine the constant of proportionality.

The linear equation represents a proportional relationship and its constant of proportionality is .

Step-by-step explanation:

A proportional relationship exists when the following relationship is observed:

Where:

- Dependent variable.

- Independent variable.

- Proportionality constant.

If and and , the following expresion is found:

The linear equation represents a proportional relationship and its constant of proportionality is .

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
