Answer:

Step-by-step explanation:
(6, 4)
x = 6 and y = 4
y > -1/2x + 7
Plug in the values to check if it is true.
4 > -1/2(6) + 7
4 > -3 + 7
4 > 4
This statement is false.
(6, 4) lies on the line.
Answer:
This is a linear function.
The others don’t make any sense so it has to be “A”.
Answer:
I suppose you mean 999^2
(1000-1)^2
which comes under the identity
(a-b)^2=
(a^2 + b^2 - 2ab)
hope this helps
