Solve the system by substitution.

y=-x^2+x-1
y=-x-1

a. (3,-4), (-1,0)
b. (-1,0), (2,-3)
c. (4,-5), (1,-1)
d. (0,-1), (2,-3)

D

Step-by-step explanation:

y = -x^2 + x - 1

y = -x -1

-x-1 = -x^2 + x -1

x^2 -2x = 0

x( x-2) = 0

x1= 0 , x2 = 2

y(0) = 0-1 = -1

y(2) = -2-1 = -3

(0, -1) & (2, -3)
