Please look in your text book for this problem Statement

Write an algebraic expression for the current situation.

                                                                              

The algebraic expression is .

First find the y intercept.

The y-intercept is the value of y, when x = 0.

                (Substitute x = 0 in original equation)

                              (Apply multiplication property of zero: )

Apply division property of equality: Divide each side by 20.

                               (Cancel common terms)

                                    (Divide: )

The y-intercept is 1000, so the graph intersects the y-axis at .

Next find the x-intercept.

The x-intercept is the value of x, when y = 0.

               (Substitute y = 0 in original equation)

                             (Apply multiplication property of zero: )

                        (Divide each side by 50)

                               (Cancel common terms)

                                      (Divide: )

The x-intercept is 400, so the graph intersects the x-axis at .

The x-intercept is 400.

The y-intercept is 1000.
