Answer 2

Answer:

The average value of y is 28.

Step-by-step explanation:

• The given equation is, y = 3x - 2.

       It represents a straight line with slope 3 and it intercepts the y-axis at -2.

• Here 'y' is a function of 'x'. With changing the value of x, y will be changed.
• The given relation between y and x is: y = 3x - 2

        The average value of x is 10. If we put the value of x in the above relation then the value of y will be evaluated.

        Putting the value of x = 10 we get, y = 3x - 2 =

                                                                    = 3(10) - 2

                                                                    = 30 - 2 = 28

        ∴ The average value of y is 28.
