Amy sells cupcakes. The graph shows a linear model for her sales times in minutes on different days. (a) What is the equation of the line, written in point-slope form? Show your work.
Step 1: Find the slope. m = y2 – y1 = - =
x2 – x1 -
Step 2: Use point (4,15) and slope (m) from step 1 and complete the equation in point-slope form.
y-y1 = m (x-x1) y - = (x - )
(b) Based on the model, how long did it initially take Amy to sell a cupcake? Approximately how much did
her sales time decreased each day?
Step 1: At 0 days, what was her sales time? minutes
Step 2: Amy’s sales time decreased minutes per day.
from point-slope form to slope-intercept form. Show your

well Amy can't sell cupcakes.

Explanation:

because she don't have a permit so off to court she goes

hello,

the steamboat is your answer.

it seems like its the only form of transportation on the choices.

the correct answer is:   "   3.6 % " .

          →   the unemployment rate is:   " 3.6 % " .

explanation:

to calculate the "unemployment rate" :

the "unemployment rate"   =

  [# of people unemployed] /   [working age population]   * 100 %   ;

                =   [9 million] / [250 million]     *   100 % ;

    →     note:   the units of "million" cancel out;

                    since:   " {million} / {million} = 1 " ;

                =   (9 / 250)   * 100 %   ;

                = 0.036 * 100 % ;

                =   3.6 %

answer:   the unemployment rate is:   " 3.6 % " .
