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 $x+3y\geq -2$

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 $x+3y\geq2$

d. There is no slope.

Step-by-step explanation:

We know that slope = $=\frac{\text{change in y coordinate}}{\text{change in x coordinate}}$

For the given table, since there is no change in x coordinate .

Thus the change in x coordinate is 0.

Therefore, slope= $=\frac{\text{change in y coordinate}}{0}=\infty$

which means the slope does not exist.

Hence, (d) is the right option. There is no slope.
