Question

Determine whether test point (-6,4) is a solution to the linear inequality x+y_<1

Answer 1

$\bf \begin{array}{llll} -6&,&4\\ \uparrow &&\uparrow \\ x&&y \end{array}\qquad x+y\le 1\implies -6+4\le 1\implies -2\le 1$

now, is it true that -2 is lesser than 1? if it's true, is a solution, if is false, is not then
