If the area of the rectangle to be drawn is 18 square units, where should points C and D be located if they lie vertically below the line that connects B and A, to make this rectangle? C(−4, −5), D(2, −5)
C(−4, −8), D(2, −8)
C(−4, −6), D(2, −6)
C(−4, −2), D(2, −2)

C(−4, −2), D(2, −2)

Step-by-step explanation:

Because the area is 18

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

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
