need help plzzzz....need this done by today

Answer 1

For this case, we must indicate which of the given graphs corresponds to the following inequality:

$y\geq 1-3x$

If we substitute the point$(x, y) = (0,0)$ we have:

$0> = 1-3 (0)\\0> = 1$

It is not met, so we discard options A and C.

It is observed that the lines of option B and D correspond to the equation$y = 1-3x$. But the dotted line of option B indicates that the region given by: $y> 1-3x$ is plotted

Thus, the region that indicates$y\geq 1-3x$ is option D

Answer:

Option D
