Question

A bakery started with 200 muffins in stock when it opened for the day. The table shows points representing the number of muffins left in stock after serving the given number of customers.
Number of customers served 0 30 60 90
Number of muffins left 200 175 150 125
Let x = the number of customers served and y = the number of muffins left.

Select each of the following equations in point-slope form that represents the number of muffins left in stock.

y−150=−65(x−60)y−150=−65(x−60)

y−150=−56(x−60)y−150=−56(x−60)

y−60=−65(x−150)y−60=−65(x−150)

y−60=56(x−150)y−60=56(x−150)

y−125=−56(x−90)y−125=−56(x−90)

y−175=−56(x−30)y−175=−56(x−30)

y−175=56(x−30)y−175=56(x−30)

y−60=−56(x−150)

Answer 1

The equation of a line going through pont (x1,y1) and the slope is m is
y-y1=m(x-x1)

find slope

sloep for 2 points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)

take 2 points
(0,200)
(30,175)
slope=(175-200)/(30-0)=-25/30=-5/6=

we can now make equations

the slope is -5/6
the given points  are
(0,200)
(30,175)
(150,60)
(90,125)

so some equations are
y-200=-5/6(x-0)
y-175=-5/6(x-30)
y-60=-5/6(x-150)
y-125=-5/6(x-90)

pick the choice with those equaitons
