Question

Which of the following ordered pairs is not a solution to the inequality y < -x + 4?

A. (1, 2)

B. (2, 1)

C. (4, 0)

D. (3, -2)

Answer 1

plug in the value for x and see if you get the value for y out of the calculation i.e.

2 = -1+4 : is this true?

Answer 2

I don't know if it s a, b, c, or d

Answer 3

try each in turn and you will find a answer that doesn't work thats the one you are looking for

Answer 4

so in this case you are looking for a value that is > the value for -x+4

Answer 5

take A. with the values (1,2) put them into the expression: 2 < -1+4
so that is 2 < 3
now this is true and a solution we need to find something like
4 < 1
thats not a solution

Answer 6

So is it C?

Answer 7

Yes is C as they are equal
