Question

Which point is NOT a solution of x + 2 y is less than or equal to 8
A. (0, 4)
B. (-2, 3)
C. (4, 4)
D. (6, 0)

Answer 1

start plugging in points.,
like
0,4
x=0, y=4

x+2y <= 8
0+2(4) <=8
8<=8
which is TRUE

hence 0,4 is the solution of the inequality
so don't mark it

repeat this for all the points

Answer 2

(-2,3) ? or (6,0) ?

Answer 3

those are TRUE, right ?
so don't mark them either!

Answer 4

only, 4,4 is FALSE,
so thats your answer :)

Answer 5

answer is C!
