Question

Which of the following is a solution of y - x < -3?

(6, 2)
(2, 6)
(2, -1)

Answer 1

(6,2)

coz if y=2 & x=6

then substitute in to the equation

and we get 2-6=-4

so -4 is less than -3; in number line. thats it!!!!!

Answer 2

(2, -1)

Explanation:

I just plugged (y-x<-3) into desmos (if you haven't used desmos, use it. Its a lifesaver) and the only coordinate pair that was part of the line, is (2,-1)

Hope that helps!
