On a blueprint, the scale indicates that 9 centimeters represent 15 feet. What is the length of a room that is 10.8 centimeters long and 6 centimeters wide on the blueprint?

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

i believe that the answer is

b. y-1=-2(x-4)

hope this !
