Question

An ice cream shop started with 80 waffle cones in stock when it opened for the day. The table shows points representing the number of waffle cones left in stock after serving the given number of customers.
Let x = the number of customers served and y = the number of waffle cones left.

Select each of the following equations in point-slope form that represents the number of waffle cones left in stock. (Choose all correct answers)

a.y−72=−23(x−12)y−72=−23(x−12)

b.y−24=23(x−64)y−24=23(x−64)

c.y−64=−23(x−24)y−64=−23(x−24)

d.y−72=−32(x−12)y−72=−32(x−12)

e.y−56=−23(x−36)y−56=−23(x−36)

f.y−24=−23(x−64)y−24=−23(x−64)

g.y−56=23(x−36)y−56=23(x−36)

h.y−36=−32(x−56)





I have attached the graph please answer ASAP

Answer 1

From  the table,
y - 72 = (64 - 72)/(24 - 12) (x - 12) = -8/12(x - 12) = -2/3(x - 12)
y - 72 = -2/3(x - 12)

y - 64 = (56 - 64)/(36 - 24) (x - 24) = -8/12 (x - 24) = -2/3(x - 24)
y - 64 = -2/3(x - 24)

y - 56 = (64 - 56)/(24 - 36) (x - 36) = 8/-12 (x - 36) = -2/3(x - 36)
y - 56 = -2/3(x - 36)
