Question

Graph: y ≤ -2

Is (-2,-7) a solution? yes or no
Is ( 2,-1) a solution? yes or no

Answer 1

(-2,-7) , yes

(2,-1) , no

Explanation:

the question says y is less than or equal to -2 . In the first order pair (-2,-7) , x= -2 & y = -7 in the number line -2 comes first than -7 it means -2 is grater than -7 so the answer is yes but in the second order pair (2,-1) the value of x is 2 and the value of y is = -1 thus -1 is grater than -2 however the question says y should be less or equal but not greater than -2 so the answer is yes for the first order pair and no for the second one
