we have

$y\leq -2x-1$ -------> inequality A

The solution of the inequality A is the shaded area below the solid blue line

y > -2x+ -------> inequality B

The solution of the inequality B is the shaded area above the dotted red line

The system has no solution

we know that

The y-intercept is the value of y when the value of x is equal to zero

The y-intercept of the red line is
(see the graph)

therefore

the equation of the inequality B is
y> -2x+2

the answer is

The number is
