Question

Tell whether (-9,2) is a solution of x+3y≥-2

Answer 1

Step-by-step explanation:

Substitute the point (-9, 2) into the inequality:

$-9+3(2)\geq 2$

Simplify:

$-3\geq -2$ False.

-3 isn't greater than or equal to -2.

(-9, 2) is not a solution of $x+3y\geq -2$

Answer 2

Answer:

Not a solution

Step-by-step explanation:

Plug the coordinates and check

$x+3y\geq-2\\\\(-9)+3(2)\stackrel{?}{\geq}-2\\\\-9+6\stackrel{?}{\geq}-2\\\\-3\stackrel{?}{\geq}-2\\\\-3\ngeq-2$

Therefore, $(-9,2)$ is not a solution of $x+3y\geq2$
