Which point lies on the line y = -2x - 3?
A (-2,-1)
B (-2,1)
c (-1, -2)
D (1,1)

B: (-2,1)

Step-by-step explanation:

Plug all the ordered pairs in:

-1=-2(-2)-3 -> 1 doesn't equal -1 so A doesn't work

1=-2(-2)-3 -> 1=1 so B does work

-2=-2(-1)-3 -> -2 doesn't equal -1 so C doesn't work

1=-2(1)-3 -> 1 doesn't equal -5 so D doesn't work

Therefore, B is the correct point

the point lies on the line y = -2x - 3 is

-2(-2) - 3 = y

4 - 3 = y

1 = y

the answer is b

Step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
